Open a Java project contains tests.
If the project structure follows src/main/java & src/test/java, commands can be found at the editor context menu. Otherwise, you can find them in the command palette.
Go to Tests will find all classes that contains the current type's name and display them in the reference view.
If only one result found, directly open that class
If no results found, user can choose generate tests or search files.
Go to Test Subjects will first remove all the Test/Tests in the type name and search types contains the replaced string.
If no results found, user can search files.
