Using Application Arguments

If your application expects arguments, you can have @SpringBootTest inject them using the args attribute.

Java
Kotlin

import org.junit.jupiter.api.Test;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.test.context.SpringBootTest;

import static org.assertj.core.api.Assertions.assertThat;

@SpringBootTest(args = "--app.test=one")
class MyApplicationArgumentTests {

	@Test
	void applicationArgumentsPopulated(@Autowired ApplicationArguments args) {
		assertThat(args.getOptionNames()).containsOnly("app.test");
		assertThat(args.getOptionValues("app.test")).containsOnly("one");
	}

}

import org.assertj.core.api.Assertions.assertThat
import org.junit.jupiter.api.Test
import org.springframework.beans.factory.annotation.Autowired
import org.springframework.boot.ApplicationArguments
import org.springframework.boot.test.context.SpringBootTest

@SpringBootTest(args = ["--app.test=one"])
class MyApplicationArgumentTests {

	@Test
	fun applicationArgumentsPopulated(@Autowired args: ApplicationArguments) {
		assertThat(args.optionNames).containsOnly("app.test")
		assertThat(args.getOptionValues("app.test")).containsOnly("one")
	}

}
