How to run unit tests¶

The dda inv test command runs Go tests. It's implementation is transitioning from being a thin wrapper around gotestsum to wrapping Bazel instead. On Linux and macos, dda inv test uses Bazel, dda inv test-legacy still being available for the gotestsum wrapper for transitional purposes. On all other platforms, dda inv test uses gotestsum, the Bazel version being available under dda inv test-new instead.

Test selection¶

The Go module to test may be selected with the -m/--module flag using a relative path, defaulting to ..

The -t/--targets flag is used to select the targets to test using a comma-separated list of relative paths within the given module. For example, the following command runs tests for the pkg/collector/check and pkg/aggregator root packages.

dda inv test --targets=pkg/collector/check,pkg/aggregator

Note

If no module nor targets are set then the tests for all modules and targets are executed, which may be time-consuming.

Race detection¶

The -r/--race flag enables Go's built-in data race detector.
