There was no easy way to automatically test the end-to-end functionality of commands, flags, environment variables etc. The need for end-to-end testing was highlighted by the issues fixed in #5341. There was no automated test to continually verify current behaviour, nor a framework to quickly test the correctness of the fixes. This change adds an end-to-end testing framework in the cmdtest folder. It has some simple examples in func TestCmdTest in cmdtest_test.go. The tests should be readable by anybody familiar with rclone and look like this: // Test the rclone version command with debug logging (-vv) out, err = rclone("version", "-vv") if assert.NoError(t, err) { assert.Contains(t, out, "rclone v") assert.Contains(t, out, "os/version:") assert.Contains(t, out, " DEBUG : ") } The end-to-end tests are executed just like the Go unit tests, that is: go test ./cmdtest -v The change also contains a thorough test of environment variables in environment_test.go. Thanks to @ncw for encouragement and introduction to the TestMain trick.
