Enhancement: Stop Pretest/posttest From Being A Dependency For Other Tests

by ADMIN 75 views

Introduction

In the current testing framework, pretest and posttest modules have become a dependency for other test modules. This has led to two major issues: other test modules rely on the configuration steps performed by pretest and posttest, and the pretest module itself is doing configuration tasks rather than actual testing. In this article, we will discuss the proposed enhancement to address these problems and improve the overall testing framework.

Current Behavior

The current behavior of the pretest and posttest modules is that they perform important configuration steps that other test modules depend on. This is evident in the following examples:

  • The QoS test will fail if the saithrift package is not installed by the pretest.
  • The TSA_TSB startup needs to be disabled in the pretest or that feature will cause tests to fail.

This behavior creates a dependency chain where other test modules rely on the pretest and posttest modules to perform their tasks. This can lead to a fragile testing framework where small changes can cause tests to fail.

Proposed Behavior

To address the issues mentioned above, the proposed behavior is to move the important configuration, initialization, and cleanup tasks to the deploy-mg module. This will ensure that the deploy-mg module is responsible for setting up the environment for testing, rather than the pretest and posttest modules.

The pretest module that actually has tests and checks can stay in the pretest file or be moved to a sanity-check or similar module. This will allow the pretest module to focus on its original purpose of testing and checking, rather than performing configuration tasks.

Benefits of the Proposed Behavior

The proposed behavior has several benefits:

  • Improved modularity: By moving the configuration tasks to the deploy-mg module, we can improve the modularity of the testing framework. Each module will have a clear responsibility, and changes will be easier to make and test.
  • Reduced dependencies: By removing the dependency on the pretest and posttest modules, other test modules will be less prone to failures due to changes in the pretest and posttest modules.
  • Simplified testing: With the pretest module focusing on testing and checking, the testing framework will become simpler and easier to understand.

Implementation Plan

To implement the proposed behavior, the following steps can be taken:

  1. Identify configuration tasks: Identify the configuration tasks that are currently performed by the pretest and posttest modules.
  2. Move configuration tasks to deploy-mg: Move the identified configuration tasks to the deploy-mg module.
  3. Refactor pretest module: Refactor the pretest module to focus on testing and checking, rather than performing configuration tasks.
  4. Test and validate: Test and validate the changes to ensure that the testing framework is working as expected.

Conclusion

In conclusion, the proposed enhancement to stop pretest/posttest from being a dependency for other tests will improve the modularity, reduce dependencies, and simplify the testing framework. By moving the configuration tasks to the deploy-mg module and refactoring the pretest module, we can create a more robust and maintainable testing framework.

Is it platform specific

The proposed enhancement is not platform-specific. The changes can be made to the testing framework without affecting the platform.

Importance or Severity

The importance or severity of the proposed enhancement is low. The changes are primarily aimed at improving the modularity and reducing dependencies in the testing framework.

Description of the enhancement

The enhancement is aimed at addressing two main problems:

  1. Other test modules have dependence on pre and posttest: The pretest and posttest modules have become a dependency for other test modules, leading to a fragile testing framework.
  2. "pretest" is a test file - but is doing config, not testing: The pretest module is doing configuration tasks rather than actual testing, which is not its original purpose.

Current Behavior

The current behavior of the pretest and posttest modules is that they perform important configuration steps that other test modules depend on.

Proposed Behavior

The proposed behavior is to move the important configuration, initialization, and cleanup tasks to the deploy-mg module. The pretest module that actually has tests and checks can stay in the pretest file or be moved to a sanity-check or similar module.

Conclusion

Q: What is the current behavior of the pretest and posttest modules?

A: The current behavior of the pretest and posttest modules is that they perform important configuration steps that other test modules depend on. This creates a dependency chain where other test modules rely on the pretest and posttest modules to perform their tasks.

Q: Why is the pretest module doing configuration tasks rather than actual testing?

A: The pretest module is doing configuration tasks rather than actual testing because it has become a dependency for other test modules. This has led to a situation where the pretest module is responsible for setting up the environment for testing, rather than its original purpose of testing and checking.

Q: What are the benefits of moving the configuration tasks to the deploy-mg module?

A: The benefits of moving the configuration tasks to the deploy-mg module include:

  • Improved modularity: By moving the configuration tasks to the deploy-mg module, we can improve the modularity of the testing framework.
  • Reduced dependencies: By removing the dependency on the pretest and posttest modules, other test modules will be less prone to failures due to changes in the pretest and posttest modules.

Q: How will the proposed behavior affect the testing framework?

A: The proposed behavior will improve the modularity, reduce dependencies, and simplify the testing framework. By moving the configuration tasks to the deploy-mg module and refactoring the pretest module, we can create a more robust and maintainable testing framework.
