Make dap.test_class() and dap.test_nearest_method() callable from nvim-dap window

[johannww]

Problem Statement

There could be a way to call test_class() and test_nearest_method from the nvim-dap window when calling the "DapNew" command.

Currently, I achieve this with the following tweak in the "ftplugin/java.lua":

-- above this line is config definition, as suggested by install instructions
local jdtls = require('jdtls')
jdtls.start_or_attach(config)


-- enabling calling nearest method and test class
-- from nvim-dap window
local jdtls_dap = require('jdtls.dap')
jdtls_dap.setup_dap()

local dap = require('dap')

local old_dap_function = dap.adapters.java
dap.adapters.java = function(callback, configDap)
    if configDap.name == "Nearest Method" then
        jdtls.test_nearest_method()
    elseif configDap.name == "Test Class" then
        jdtls.test_class()
    else
        old_dap_function(callback, configDap)
    end
end

dap.configurations.java = {
    {
        type = 'java',
        request = 'launch',
        name = "Nearest Method",
    },
    {
        type = 'java',
        request = 'launch',
        name = "Test Class",
    }
}

Ideas or possible solutions

• implementing a similar logic as in the tweaked debug adapter in start_debug_adapter()
• Adding the dap.configurations in setup_dap
• Perhaps, add another function to create the Nearest Method and Test Class configurations.
