Suppose you're testing a package with multiple test files. How can you ensure that all test files are executed when running unit tests?

In Go, you can ensure that all test files are executed when running unit tests by using the go test ./... command. This command recursively tests all packages and subpackages within the current directory. Specifying all test files explicitly when running go test may be cumbersome and error-prone, especially in projects with numerous test files. The go test -run all command doesn't exist in Go and wouldn't serve this purpose. Ensuring that each test file imports the main package wouldn't guarantee that all test files are executed, as some may not have test functions. Therefore, using go test ./... is the recommended approach to test all files in a package.
