test

• Test files are defined with *_test.go suffix. Files that do not obey this pattern will not be executed as tests.
• When running tests, only the TestXxx(t *testing.T) functions are executed
• In order to run module-wide tests you need go.mod file that defines your module (your project)
• Go tests are always intended to be run via go test. Calling tests by other means (e.g., via your code itself) may be possible, but not supported

# Run tests for the current module

# run a specific test function
