6 years ago I'm the OP of that stackoverflow thread. I got this working but forgot to update the thread.
There may be better ways but this is how I got it working.
You first need to override the default shell application runner to avoid getting stuck in the jline loop. You can do this by defining your own such as:
@Component
public class CliAppRunner implements ApplicationRunner {
public CliAppRunner() {
}
@Override
public void run(ApplicationArguments args) throws Exception {
//do nothing
}
}
Note that you will have to associate this custom Application runner against a "Test" profile so it overrides only during integration testing.
You then can write a test like this:
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes =CliConfig.class)
public class ShellCommandIntegrationTest {
@Autowired
private Shell shell;
@Test
public void runTest(){
Object result=shell.evaluate(new Input(){
@Override
public String rawText() {
return "add 1 3";
}
});
DefaultResultHandler resulthandler=new DefaultResultHandler();
resulthandler.handleResult(result);
}
}
Note that the above test does not Assert anything. You will probably have to write your own little implementation of the ResultHandler interface that deals with parsing/formatting of the result so that it can be asserted.
Hope it helps.

Hey, I just stumbled upon Spring Shell recently and I am unable to get a
@SpringBootTesttest to execute. The test attempts to begin, but hangs in the IntelliJ console as if a shell has been created and waiting for input.Test:
Console:
Here's a link to my tiny repo that acts as the simplest way to reproduce this issue: https://github.com/jgreub/bowling-game-kata I'm trying to use Spring Shell 2.0.0.M2 with Spring Boot 1.5.8.RELEASE
As a follow up
When it comes to actually testing a
@ShellMethod, this stackoverflow post claims you use theShell#evaluate()method. How do you obtain an instance ofShellin a test?
