There is a new command in town in the CommandBox 3.7 snapshot build. If you want to get the current snapshot build of CommandBox 3.7 to try this out, and play with it, simply run the following command and it will direct you to the latest bleeding edge download page:
CommandBox> upgrade --latest
What does it do?
This command is called testbox watch and it is similar to testbox run which can be used to run your projects unit or integration tests. The difference is that testbox run will run your tests a single time right then, whereas the testbox watch command will stay running until you stop it with Ctrl+C. The command will watch the files in your project for changes, and every time you save a CFC file, it will run your tests immediately, outputting the results to the console window. This gives you instant feedback as you develop as to whether you just broke something.
CommandBox> testbox watch

Configuring Your Watcher
CommandBox> testbox watch help
You will see that there are a handful of way to configure how it runs. The watcher itself can be controlled by setting up the parameters you want in your box.json file for the project. Here's a rundown of the configuration elements you can set. All of these are optional except the testbox.runner.
Where are your tests located?
CommandBox> package set testbox.runner=http://localhost:8080/tests/runner.cfm
Do you want verbose test output, or compact?
CommandBox> package set testbox.verbose=false
Only runs tests with these labels
CommandBox> package set testbox.labels=foo
Choose the test suites to execute
CommandBox> package set testbox.testSuites=bar
Control how often the watcher checks the file system for changes.
CommandBox> package set testbox.watchDelay=1000
Customize exactly what files to watch for changes with a list of globbing patterns
CommandBox> package set testbox.watchPaths=/models/**.cfc
Your box.json file
So your box.json file may look something like this once you've set it up.
{
"testbox":{
"runner":"http://localhost:8080/tests/runner.cfm",
"labels":"foo",
"bundles":"test.specs",
"testSuites":"bar",
"verbose":"false",
"watchDelay":"1000",
"watchPaths":"/models/**.cfc"
}
}
