Go has a lightweight testing framework.

Their doc covered how you can start writing your tests. And you can read more on the testing package.

But there are a few important things they didn’t tell you.

Run All Tests

To run tests (in the directory you are in), simply run go test.

To specify a package directory, you have to run go test But that does not include tests in subdirectories.

To run all tests in all package directories including the subdirectories, you have to run:

go test ./...

Tests are run in package directory

But note: all tests are run with the package directory as the working directory.

In other words, take note if you are using os.Getwd() or equivalent.

You mind think the working directory is where you run go test ./.... But no. The working directory is the directory that the test is in.
