Keyboard shortcut for running unit tests

[boaz-chen]

Currently, in order to run a unit test from within vscode, one must use the mouse, hover over the test function name they care about, and click Run Test. This is not very accessible, and also hurts the workflow of keyboard oriented developers.

I would like to suggest adding an action (that can have a keyboard shortcut attached to) called: Run selected test. This test will run the test the keyboard cursor is currently on.

Thanks for all the hard work!

This would be hugely useful. Furthermore, a similar keyboard shortcut to run all tests in the current file (i.e. click the "Run Test" label at the top of the file) would be similarly useful.

If I am not missing anything, the VS Code action called

“Rust Analyzer: Run”

is doing exactly this, and has been there since forever. The action is documented here:

https://rust-analyzer.github.io/manual.html#run

To bind it to a shortcut, use this config:

https://github.com/matklad/config/blob/caedcf2cb24dac5154b9e081240b0019382d3ec9/home/.config/Code/User/keybindings.json#L6

The command 'rust-analyzer.run' adds a little complexity to the process of running the selected test. It first prompts the user to select a runnable that they want to execute, this can include tests and a number of other possible actions.

The ask was explicitly for a command that would immediately run the selected test. While the existing run command allows the user to accomplish running the test without using the mouse, this new run selected test command would minimize the actions a user has to take.

See run command.

+1

+1. This would be extremely useful. 'rust-analyzer.run' is not sufficient. The goal would be to bind a key to the 'Run Test' or 'Run Tests' button.

I think this can be handled on the type-script side. Basically, we should add an optional argument to rust-analyzer.run command. Something like ?mode: "rerun" | "selection", where "rerun" make it rerun last task, and "selection" makes it run the selected thing.

There is also a very useful "Tasks: Rerun last task" VS Code command that can be triggered with the keyboard after running the test with the mouse once.
