Run TestNG xml suites in debug mode

[anjerukare]

Hello, I'm looking for a way to run TestNG xml suites in debug mode.

Now I know how to just run TestNG xml suites by specifying jar package:

java -cp [path-to-jar] org.testng.TestNG [path-to-xml-suite]

I also found parameter that allows to debug it remotely: -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=1044.

I guess next step is attaching. How can I attach to debug session from Neovim?

You need to create an attach configuration:

local dap = require('dap')
dap.configurations.java = {
  {
    type = 'java';
    request = 'attach';
    name = "Debug (Attach) - Remote";
    hostName = "127.0.0.1";
    port = 1044;
  },
}

The port must match whatever you're using in address=1044
See https://github.com/mfussenegger/nvim-dap/wiki/Java#configuration

If you're using a multi-module project you'll also have to add a projectName = '<yourproject>' property.

You might want to change suspend=n to suspend=y to ensure it waits for a debugger to attach before running.

If you follow the vscode-java-test setup instructions (https://github.com/mfussenegger/nvim-jdtls#vscode-java-test-installation) you should also be able to use: require'jdtls'.test_class() and require'jdtls'.test_nearest_method() to trigger tests directly from within neovim
