Debug Rails test

[davidvalaz]

I wondered if anyone has some working config they could share about how to debug a Rails app and initiate a debugging session from a test file?

Right now mine just runs the test and doesn't wait at the breakpoint. Even if the breakpoint is in the test file.

My config is:

dap.adapters.ruby = {
    type = "executable",
    command = "bundle",
    args = { "exec", "readapt", "stdio" },
}
dap.configurations.ruby = {
    {
        type = "ruby",
        request = "launch",
        name = "Minitest",
        program = "bundle",
        programArgs = {
            "exec",
            "rails",
            "test",
            "${file}"
        }
    },
}
