Fix TestMain cleanup issue #1542

[Favy217]

###Purpose or design rationale of this PR

What does this PR do?
This PR fixes the cleanup issue in the TestMain function by ensuring that the test containers are properly released and the program exits with the correct status code after running the tests.

Why does it do it?
The issue was causing improper resource cleanup, which could lead to resource leakage or incomplete test runs. This PR ensures the proper cleanup and exit of the test suite.

How does it do it?
The TestMain function is updated to call m.Run() before the defer statements and to exit properly with the status code returned by m.Run().

###Deployment tag versioning
No, this PR doesn't involve a new deployment, git tag, docker image tag

###Breaking change label
No, this PR is not a breaking change

Summary by CodeRabbit

• Bug Fixes

Walkthrough

The changes in this pull request modify the TestMain function in the rollup/tests/bridge_test.go file. A line is added to capture the exit code from m.Run() before the deferred cleanup function, ensuring the program exits with the correct status after the tests. The cleanup logic for testApps and rollupApp remains unchanged, and the final line now calls os.Exit(code) to use the captured exit code.

66-75: Excellent fix for the TestMain cleanup issue!

The changes effectively address the cleanup issue mentioned in the PR objectives. Here's a breakdown of the improvements:

1. Capturing the exit code from m.Run() ensures that the test results are preserved.
2. The deferred cleanup function remains in place, guaranteeing that resources are properly released after the tests complete.
3. Using os.Exit(code) at the end ensures that the program exits with the correct status code based on the test results.

This implementation resolves the potential issue of losing the test status due to premature exit or cleanup. It maintains the correct order of operations: run tests, capture results, perform cleanup, and then exit with the appropriate status.

Line range hint 214-226: Verify independence of subtests in TestFunction

While the changes in TestMain improve the cleanup process, it's important to ensure that the subtests in TestFunction are independent and don't rely on side effects from previous tests. This is especially crucial now that we have a more robust cleanup mechanism.

Consider reviewing each subtest to confirm:

1. They can run independently without relying on state from previous tests.
2. They properly set up and tear down any necessary test environment.
3. They don't have unintended side effects that could impact subsequent tests.

This will help maintain the reliability and consistency of the test suite with the improved cleanup process.

To help verify the independence of subtests, you can run the following command:

This will help identify the subtests and their associated function calls, allowing for a closer examination of potential dependencies or shared state.
