The library will +provide tabular data structures (similar to DataFrame and Series) and +support common operations needed by scientists and engineers working +with structured data. Major functional goals include: + +- **Handling missing data:** The system should represent missing values as + NaN, NA or NaT and propagate them through computations. This + capability simplifies data cleaning and statistical analysis by + preventing silent errors software.com. + +- **Size mutability:** Users should be able to insert or delete columns + and rows in data structures. Dynamic resizing is central to + interactive analysis workflows where the shape of a table evolves as + new information becomes available raw.githubusercontent.com. + +- **Automatic and explicit data alignment:** When performing + arithmetic or merging operations, the system will align data on + labels or allow users to opt out of alignment entirely. Proper + alignment prevents accidental mismatches and promotes reproducible + results raw.githubusercontent.com. + +- **Flexible group-by operations:** The library should implement + split–apply–combine patterns for aggregation, transformation, and + filtering so that users can summarise data by categories with a + single fluent expression raw.githubusercontent.com. + +- **Robust I/O tooling:** Data structures must load from and save to + common file formats (CSV, Excel) and efficiently persist to + high-performance formats such as HDF5 raw.githubusercontent.com. + +- **Time-series functionality:** Operations like date-range generation, + frequency conversion, moving-window statistics and date shifting will + be built in so that time-indexed data can be analysed without + external libraries raw.githubusercontent.com. + +In addition to these functional requirements, the project emphasises +non-functional qualities such as performance, flexibility and +expressive APIs. The goal is to provide an intuitive open-source tool +that researchers can use to analyse data without sacrificing speed or +power raw.githubusercontent.com. + +--- + +## Key Quality Metrics + +To ensure that the implementation is maintainable and testable, we will +track several quality metrics throughout the project lifecycle. The +metrics were selected based on guidance from software engineering +literature and industry best practices. + +### Maintainability metrics + +- **Maintainability index (MI):** Visual Studio defines an index from + 0 to 100 that summarises the ease of maintaining a piece of code. + Higher values indicate more maintainable code, with scores above + 20 considered “good,” 10–19 “moderate” and below 10 “poor” + learn.microsoft.com. + MI combines several measurements such as cyclomatic complexity, + depth of inheritance and class coupling. Although we do not + compute MI directly, we monitor its constituent components to track + trends over time. + +- **Cyclomatic complexity:** This measures the number of linearly + independent paths through a program. Each decision point (e.g., + if, for, while) adds one to the count. Higher complexity + indicates more potential execution paths and requires more tests to + achieve full coverage learn.microsoft.com. Our metrics script + approximates cyclomatic complexity by scanning for decision + keywords, providing a reproducible indicator of structural + complexity. + +- **Comment-to-code ratio:** The number of comment lines divided by + the number of executable lines software.com. Comments + capture design assumptions, edge cases and rationale that are not + obvious from code alone. A moderate ratio improves maintainability + by aiding knowledge transfer and reducing ramp-up time for new + contributors software.com. However, excessively high + ratios can reflect commented-out code or verbose documentation, + so the ratio should be interpreted in context software.com. + +- **Average function length:** Smaller functions tend to perform a + single task, are easier to understand and thus easier to modify. + The metrics script measures the average number of code lines per + function. Keeping this metric low encourages modular design and + aligns with the Single Responsibility Principle. + +- **Class coupling and depth of inheritance:** Although our project + uses primarily functions and data structures, we will monitor + coupling and inheritance depth where applicable. Visual Studio’s + guidance notes that high class coupling and deep inheritance trees + decrease maintainability learn.microsoft.com. We will + minimise dependencies between modules and favour composition over + inheritance to keep these metrics low. + +### Testability metrics + +- **Test coverage:** Atlassian describes code coverage as a measure + of how much of the code base is exercised by tests and notes + several metrics: function, statement, branch, condition and line + coverage atlassian.com. Although a high coverage + percentage does not guarantee good tests, it reveals which parts of + the system remain untested and helps to prioritise additional + testing efforts. Since we cannot run external coverage tools in + this environment, our metrics script approximates test effort by + reporting the ratio of lines in test files to total lines of code + and counting the number of test functions. Increasing the + test-to-code ratio over time should correlate with improved + coverage. + +- **Number of test cases:** We treat each test_* function in + Python and calls to describe/it in JavaScript as individual + test cases. Tracking the number of test cases encourages + developers to write focused, granular tests and highlights + subsystems that may need additional verification. + +- **Complexity vs. tests:** Cyclomatic complexity informs us how + many test cases are theoretically required to exercise all + execution paths learn.microsoft.com. By comparing the number + of test cases to the aggregate complexity of the code base, we can + judge whether testing is keeping pace with growing code + intricacy. If complexity rises faster than test counts, there may + be untested paths that warrant attention. + +--- + +## Using the metrics + +The `metrics_collector.py` script in `courseProjectCode/Metrics/` +implements the measurements described above. Running the script +generates a JSON report containing per-file metrics and a summary. +These metrics will form the basis of our quality dashboard and guide +refactoring and testing priorities throughout the project. By +monitoring comment ratios, function lengths, complexity and test +ratios, we can make data-driven decisions to keep the code base +maintainable and to ensure that behaviour is thoroughly validated. diff --git a/courseProjectDocs/Setup/Coverage report.pdf b/courseProjectDocs/Setup/Coverage report.pdf new file mode 100644 index 0000000000000..711e60f3fa946 Binary files /dev/null and b/courseProjectDocs/Setup/Coverage report.pdf differ diff --git a/courseProjectDocs/Setup/README.md b/courseProjectDocs/Setup/README.md new file mode 100644 index 0000000000000..b8598f477fa35 --- /dev/null +++ b/courseProjectDocs/Setup/README.md @@ -0,0 +1,82 @@ +# Pandas Baseline Build & Test Setup + +This document provides instructions for reproducing the pandas baseline build and test results. + +## Environment Setup + +### Prerequisites +- Python 3.13.5 +- Virtual environment support + + +### Step-by-Step Setup + +1. **Clone the Repository** + ```bash + git clone https://github.com/saisandeepramavath/SWEN_777_Pandas.git + cd SWEN_777_Pandas + ``` + +2. **Create and Activate Virtual Environment** + ```bash + python3 -m venv venv + source venv/bin/activate + ``` + +3. **Upgrade pip** + ```bash + pip install --upgrade pip + ``` + +4. **Install Dependencies** + ```bash + pip install -r requirements-dev.txt + ``` + +## Running Tests + +### Comprehensive Test Suite +To reproduce the test results, run the following command: + +```bash +python -m pytest pandas/tests/series/test_constructors.py pandas/tests/frame/test_constructors.py pandas/tests/test_nanops.py pandas/tests/series/methods/test_dropna.py pandas/tests/frame/methods/test_dropna.py -v --cov=pandas --cov-report=html:courseProjectDocs/Setup/htmlcov --cov-report=term +``` + +### Individual Test Modules +You can also run individual test modules: + +```bash +# Series constructors +python -m pytest pandas/tests/series/test_constructors.py -v + +# DataFrame constructors +python -m pytest pandas/tests/frame/test_constructors.py -v + +# Numerical operations +python -m pytest pandas/tests/test_nanops.py -v + +# Missing data handling +python -m pytest pandas/tests/series/methods/test_dropna.py pandas/tests/frame/methods/test_dropna.py -v +``` + +## Test Results Overview + +The test suite executed includes: +- **Series Constructor Tests**: Core pandas Series creation and initialization +- **DataFrame Constructor Tests**: Core pandas DataFrame creation and initialization +- **Numerical Operations Tests**: Mathematical operations and statistical functions +- **Missing Data Tests**: NA/NaN value handling and dropna functionality + +## Coverage Report + +The HTML coverage report is generated in `courseProjectDocs/Setup/htmlcov/index.html`. +Open this file in a web browser to view detailed coverage information. + + + +## Additional Information + +- **Test Framework**: pytest with coverage reporting +- **Build System**: Meson + Ninja (pandas development build) +- **Python Version**: 3.13.5 +- **Test Categories**: Unit tests focusing on core functionality \ No newline at end of file diff --git a/courseProjectDocs/Setup/report.md b/courseProjectDocs/Setup/report.md new file mode 100644 index 0000000000000..04aa729b80982 --- /dev/null +++ b/courseProjectDocs/Setup/report.md @@ -0,0 +1,196 @@ +# Pandas Baseline Build & Test Report + +## Environment Setup Documentation + +### System Information +- **Operating System**: macOS (Darwin) +- **Python Version**: 3.13.5 +- **Architecture**: x86_64 / ARM64 compatible +- **Shell**: zsh +- **Date**: October 6, 2025 + +### Development Environment Configuration + +#### Virtual Environment Setup +```bash +Python: 3.13.5 +Virtual Environment: venv (created using python3 -m venv) +Package Manager: pip 25.2 +``` + +#### Key Dependencies Installed +```bash +pandas: 3.0.0.dev0+2352.g603f06f82a (development version) +pytest: 8.4.2 +pytest-cov: 7.0.0 +numpy: 2.3.3 +python-dateutil: 2.9.0.post0 +``` + +#### Build System +```bash +Build Tool: Meson 1.2.1 +Ninja: 1.13.0 +Compiler: Apple clang version 17.0.0 +``` + +## Test Suite Summary + +### Test Categories Executed + +#### 1.

Behavior) | +|----------------|--------------------------|----------------------------------| +| **FR-1** | Handle missing data with NaN/NA/NaT representations | When a DataFrame column contains a missing value, the system should represent it as NaN (or NA/NaT for date types) and subsequent computations should treat the value as missing. | +| **FR-2** | Support size mutability – columns can be inserted/deleted | After inserting a new column into a DataFrame, the number of columns increases and the new column is accessible by label; after deleting it, the column should no longer exist and the shape of the DataFrame reflects the removal. | +| **FR-3** | Automatic and explicit data alignment across objects | When adding two Series objects with misaligned indexes, the system should align on index labels and introduce missing values where labels do not match. | +| **FR-4** | Provide flexible group-by functionality | When grouping a DataFrame by a categorical column and applying a sum aggregation, the resulting object should contain aggregated sums for each group that equal the sum of values in the original DataFrame for that group. | +| **FR-5** | Robust I/O tools for loading and saving data | Reading a CSV file containing 100 rows and 5 columns should create a DataFrame with 100 rows and 5 columns and values that match the file; saving to HDF5 and then reloading should yield an identical DataFrame. | +| **FR-6** | Time-series-specific functionality | Generating a date range between “2023-01-01” and “2023-01-10” with a daily frequency should produce a sequence of 10 dates; shifting the resulting series by one period should move each date forward by one day. | +| **NFR-1** | Provide fast, flexible and expressive data structures | Creating and slicing a DataFrame with 10,000 rows should complete within an acceptable threshold (e.g., under 50 ms) in standard hardware, reflecting expected performance. | +| **NFR-2** | Be a powerful and flexible open-source data analysis tool | The API should allow users to chain multiple operations (e.g., filtering, grouping and aggregation) in a single fluent expression; the resulting code should remain readable and the operations should execute correctly. | +| **NFR-3** | Provide robust I/O capabilities | Loading a large CSV file (e.g., 1 GB) and saving it to HDF5 should not crash and should complete without data corruption; memory usage should remain within reasonable bounds relative to the file size. | diff --git a/courseProjectDocs/static-analysis/report.md b/courseProjectDocs/static-analysis/report.md new

Assigning error messages to variables before raising exceptions improves code maintainability, makes testing easier, and follows Python best practices for exception handling. + +--- + +### Fix #2:

• pandas library installed and functional
• Write permissions in test directory | +| **Test Steps** | **Step 1:** Create DataFrame with mixed data types using public API
  - Create DataFrame with 5 columns: id (int), name (string), score (float), date (datetime), active (boolean)
  - Use pandas constructor: `pd.DataFrame()`

**Step 2:** Export DataFrame to CSV file
  - Call `to_csv()` method with file path
  - Use `index=False` parameter
  - Verify file creation on disk

**Step 3:** Import CSV file back into new DataFrame
  - Call `pd.read_csv()` with file path
  - Use `parse_dates` parameter for date column

**Step 4:** Verify data integrity and type preservation
  - Check row count matches original (5 rows)
  - Verify column names preserved
  - Compare all values with original data
  - Verify datetime type correctly parsed | +| **Expected Results** | • CSV file created successfully at specified path
• File contains 5 data rows plus header
• Data round-trips without any loss
• Integer values: [1, 2, 3, 4, 5] preserved
• String values: ['Alice', 'Bob', 'Charlie', 'David', 'Eve'] preserved
• Float values: [95.5, 87.3, 92.1, 88.7, 91.4] preserved
• Boolean values: [True, False, True, True, False] preserved
• Date column recognized as datetime64 type
• All assertions pass without errors | +| **Actual Results** | **PASSED** - All expected results achieved | + +--- + +### Test Case 2: Missing Data Cleaning Workflow + +**Test ID:** SYS-002 +**Owner:** Nithikesh Bobbili +**Category:** Data Cleaning Workflow +**Test File:** `pandas/tests/system/test_system_workflows.py::TestDataCleaningWorkflow::test_missing_data_handling_workflow` + +| Attribute | Details | +|-----------|---------| +| **Title** | Missing Data Cleaning Workflow | +| **Pre-conditions** | • pandas library available
• numpy library available for NaN values
• No external dependencies or files required | +| **Test Steps** | **Step 1:** Create DataFrame with missing values using public API
  - Create 3-column DataFrame with `np.nan` values
  - Column A: 2 missing values at positions 1 and 3
  - Column B: 2 missing values at positions 0 and 2
  - Column C: 1 missing value at position 4

**Step 2:** Detect missing values using public methods
  - Call `isnull()` to create boolean mask
  - Call `sum()` to count missing values per column
  - Verify counts: A=2, B=2, C=1

**Step 3:** Fill missing values using multiple strategies
  - **Strategy 3a:** Forward fill using `ffill()`
    - Verify propagation of last valid value
    - Check remaining NaN count
  - **Strategy 3b:** Backward fill using `bfill()`
    - Verify propagation of next valid value
    - Check remaining NaN count
  - **Strategy 3c:** Constant fill using `fillna(0)`
    - Verify all NaN replaced with 0

**Step 4:** Verify all missing values handled correctly
  - Confirm no NaN values remain after constant fill
  - Verify DataFrame shape preserved
  - Check specific filled values match expectations | +| **Expected Results** | • Missing values correctly identified: A=2, B=2, C=1 (total 5)
• Forward fill leaves 1 NaN (at first position of column B)
• Forward fill propagates value correctly (row 1, col A = 1.0)
• Backward fill leaves 1 NaN (at last position of column C)
• Backward fill propagates value correctly (row 0, col B = 2.0)
• Constant fill (value=0) removes all NaN values
• Constant fill replaces NaN with exact value (row 1, col A = 0.0)
• DataFrame shape (5, 3) preserved after all operations
• All assertions pass without errors | +| **Actual Results** | **PASSED** - All expected results achieved | + +--- + +### Test Case 3: Group-by Aggregation Analysis Workflow + +**Test ID:** SYS-003 +**Owner:** Mallikarjuna +**Category:** Aggregation and Analysis Workflow +**Test File:** `pandas/tests/system/test_system_workflows.py::TestAggregationWorkflow::test_groupby_aggregation_workflow` + +| Attribute | Details | +|-----------|---------| +| **Title** | Group-by Aggregation Analysis Workflow | +| **Pre-conditions** | • pandas library functional
• Sufficient memory for group operations
• No external data sources required | +| **Test Steps** | **Step 1:** Create DataFrame with categorical and numeric data
  - Create DataFrame with 3 columns:
    - category: ['A', 'B', 'A', 'B', 'A', 'B', 'A', 'B']
    - value: [10, 20, 15, 25, 20, 30, 25, 35]
    - quantity: [1, 2, 3, 4, 5, 6, 7, 8]
  - Total 8 rows, evenly split between categories A and B

**Step 2:** Group data by category using public API
  - Call `groupby('category')` on DataFrame
  - Store grouped object for multiple operations

**Step 3:** Apply multiple aggregation functions
  - **Step 3a:** Apply mean aggregation on 'value' column
    - Calculate average for each category
    - Verify: Category A mean = 17.5, Category B mean = 27.5
  - **Step 3b:** Apply sum aggregation on 'value' column
    - Calculate total for each category
    - Verify: Category A sum = 70, Category B sum = 110
  - **Step 3c:** Apply count aggregation
    - Count items in each category using `size()`
    - Verify: Category A count = 4, Category B count = 4

**Step 4:** Apply multiple aggregations simultaneously
  - Use `agg(['mean', 'sum', 'count'])` on grouped data
  - Create multi-column result DataFrame

**Step 5:** Verify aggregated results comprehensively
  - Check all 6 values (2 categories × 3 aggregations)
  - Verify result DataFrame shape is (2, 3)
  - Confirm index contains category labels | +| **Expected Results** | • Data groups correctly into 2 categories (A and B)
• Category A mean aggregation: (10+15+20+25)/4 = 17.5 ✓
• Category B mean aggregation: (20+25+30+35)/4 = 27.5 ✓
• Category A sum aggregation: 10+15+20+25 = 70 ✓
• Category B sum aggregation: 20+25+30+35 = 110 ✓
• Category A count: 4 items ✓
• Category B count: 4 items ✓
• Multi-aggregation creates DataFrame with shape (2, 3)
• Multi-aggregation preserves all individual results
• Result index contains 'A' and 'B' as category labels
• Result columns contain 'mean', 'sum', 'count'
• All assertions pass without errors | +| **Actual Results** | **PASSED** - All expected results achieved | + +--- + +## Execution and Results + +### Test Environment + +**Test File:**
