How to Set the Working Directory for Your Go Tests?

Working Directory in Go Tests

In Go, it's common to place configuration files in the working directory and reference them in the code. However, unit tests may fail to find these files if the test environment doesn't match the production one.

To specify a working directory for your Go tests, explore the following solution:

Consider using the Caller function from the runtime package. Caller takes the current test source file and returns its path. This path can be used to set the working directory for the test:

<code class="go">package sample

import (
    "testing"
    "runtime"
    "os"
)

func TestGetDirectory(t *testing.T) {
    _, filename, _, _ := runtime.Caller(0)
    dir := filepath.Dir(filename)
    os.Chdir(dir)
    // Run tests using configuration files in the modified working directory
}</code>
Copy after login

By using Caller, you can obtain the path to the current test source file and set the working directory accordingly. This allows your tests to locate configuration files in the same directory as the test code, which should resolve the file-not-found errors.
