如果您尝试显示换行符,JUnit的Parameterized Tests将无声地失败,这是一个众所周知的错误:https://bugs.eclipse.org/bugs/show_bug.cgi?id=474465
import static org.junit.Assert.assertEquals;
import java.util.Arrays;
import java.util.Collection;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.Parameterized;
import org.junit.runners.Parameterized.Parameters;
@RunWith(Parameterized.class)
public class Example {
private String actual;
private String expected;
public Example(String actual, String expected) {
this.actual = actual;
this.expected = expected;
}
@Parameters(name = "{0}") // can't do this ("\n" not allowed)
public static Collection<Object[]> testCollection() {
return Arrays.asList(new Object[][] {
{ "Hello\nWorld", "Hello\nWorld" }
});
}
@Test
public void test() {
assertEquals(expected, actual);
}
}
这个问题是否有任何已知的解决方法?例如,有没有办法在这里替换换行符:@Parameters(name = "{0}")
,但实际上不在测试本身?
答案 0 :(得分:1)
您需要双击斜杠,例如\\n
