Provide option for watching files with '--watch' option

[vysinsky]

Do you plan to add support for --watch attribute? Or do you think it is better to use built-in file watchers and trigger tests from the file watcher?

What are you trying to achieve? How it should look like?

[fprochazka]

Imho he wants to run the tests automatically, on save.

[vysinsky]

Exactly. But I've realized that I can set file watcher. So it is probably not necessary to add it to the plug-in.

Please clould you provide tutorial/link how to do that? Thanks!

It would be nice to have it in the plugin, but Tester watches in one while (TRUE) {} process and implementation-wise, I have no clue how to tell that one run of the tests has ended or that another one has started, and re-create the test console for the next run.

I do not see any value in implementing --watch over FileWatchers in IDE. When you change code, tests run again. Result is the same. Do I miss something here?

File Watchers are meant for compiling various things like SCSS in the background, it even says so in the docs. Thus, they can only launch binaries directly, not Run Configurations, so while yes, you can set a up a watcher to run Tester, all you get from it is a raw console output, without the added value of the plugin features. Result is the same as running tester --watch in the terminal.
