Response

Certainly! I'll implement the test suite for the progress.go file as requested. Let's break this down into steps and create the necessary code changes.

File & User Request Examination

The user has requested to create a comprehensive test suite for the progress.go file. This involves creating a new file progress_test.go and implementing test cases for the Progress struct and its methods (Increment() and GetProgress()), as well as the displayProgress() function. We'll need to ensure thread safety, mock time.Sleep, and capture stdout for testing.

Implement the User's Request

Let's create the test suite step by step.

First, we'll create the new progress_test.go file:

`progress_test.go`

These changes implement a comprehensive test suite for the progress.go file, addressing all the requirements specified in the user's request. Let's break down the implementation:

We created a new file progress_test.go with the following test cases:
- TestProgressIncrement: Tests the Increment() method.
- TestProgressGetProgress: Tests the GetProgress() method.
- TestProgressConcurrency: Checks thread safety with concurrent increments.
- TestDisplayProgress: Tests the displayProgress() function, including mocking time.Sleep and capturing stdout.
The tests cover all the requested scenarios:
- Verifying that the processedFiles count increases correctly.
- Checking thread safety with concurrent increments.
- Ensuring GetProgress() returns correct values.
- Verifying thread safety when called concurrently with Increment().
- Mocking time.Sleep to avoid long test durations.
- Capturing stdout to verify correct output format.
- Testing early termination when processed >= total.
We updated the README.md file to mention the new test suite and provide instructions on how to run the tests.

These changes provide a robust test suite for the progress.go file, ensuring its functionality and thread safety.
