Improve Modelchecker Testability

by ADMIN 33 views

Introduction

The modelchecker is a crucial component of our software development process, ensuring that our code meets the required standards and guidelines. However, the current testing framework for the modelchecker has several limitations, making it difficult to ensure the reliability and accuracy of the modelchecker. In this article, we will discuss the current state of the modelchecker testing framework and propose improvements to make it more robust and efficient.

Current Testing Framework

The modelchecker currently contains the following types of tests:

Unit Tests for Generic Checks

  • QueryCheck: These unit tests cover the basic functionality of the generic checks, such as checking for query syntax and query semantics. However, these tests do not cover the specific use cases of the generic checks, which are used to create new checks.

Unit Tests for Specific Checks

  • These unit tests cover the specific checks, such as checking for specific syntax or semantics. However, these tests do not cover the generic checks used to create these specific checks.

Tests to Run the Modelchecker Locally

  • These tests allow us to run the modelchecker locally and verify its functionality. However, these tests do not cover the edge cases or the specific use cases of the modelchecker.

Tests to Confirm that Check Messages Work

  • These tests verify that the check messages are displayed correctly. However, these tests do not cover the specific use cases of the check messages.

Limitations of the Current Testing Framework

The current testing framework has several limitations, making it difficult to ensure the reliability and accuracy of the modelchecker. Some of the limitations are:

  • Lack of Testing for New Checks: The current testing framework does not cover new checks that use the generic checks. This means that new checks are not thoroughly tested, which can lead to errors and bugs in the modelchecker.
  • Single Schematisation: The current testing framework uses a single schematisation to test whether the modelchecker does not fail. However, this schematisation cannot reflect all possible cases, which can lead to missed issues.
  • Limited Coverage: The current testing framework does not cover all possible use cases of the modelchecker, which can lead to errors and bugs.

Proposed Improvements

To improve the modelchecker testability, we propose the following improvements:

1. Automated Testing for New Checks

  • We propose to create a mechanism to automatically generate tests for new checks that use the generic checks. This can be done by creating a template for the tests and filling in the specific details of the new check.
  • This will ensure that new checks are thoroughly tested, which will reduce the likelihood of errors and bugs in the modelchecker.

2. Multiple Schematisations

  • We propose to create multiple schematisations to test whether the modelchecker does not fail. This will ensure that all possible cases are covered, which will reduce the likelihood of missed issues.
  • We can use a combination of manual and automated testing to create multiple schematisations.

3. Improved Coverage

  • We propose to improve the coverage of the modelchecker testing framework by covering all possible use cases of the modelchecker.
  • We can use a combination of manual and automated testing to improve the coverage.

Implementation

To implement the proposed improvements, we will need to make the following changes:

1. Create a Mechanism for Automated Testing

  • We will need to create a template for the tests and fill in the specific details of the new check.
  • We will need to integrate the automated testing mechanism with the existing testing framework.

2. Create Multiple Schematisations

  • We will need to create multiple schematisations to test whether the modelchecker does not fail.
  • We will need to integrate the multiple schematisations with the existing testing framework.

3. Improve Coverage

  • We will need to improve the coverage of the modelchecker testing framework by covering all possible use cases of the modelchecker.
  • We will need to integrate the improved coverage with the existing testing framework.

Conclusion

The current testing framework for the modelchecker has several limitations, making it difficult to ensure the reliability and accuracy of the modelchecker. To improve the modelchecker testability, we propose the following improvements:

  • Automated testing for new checks
  • Multiple schematisations
  • Improved coverage
