Question

我像这样进行理论测试

@Theory
public void qlIsNotNullAndReservationWithRefIdDoesntHaveItemReference(
        @TestedOn(ints = {100, 200, 300}) final int value) {

    assertTrue("should be no error", false);
}

它总是会在ParameterizedAssertionError错误中结束而没有任何有意义的消息。

因为无论如何要显示消息的“正确”失败？

Answer 1

我试过这个：

package com.junit.theory;

import static org.junit.Assert.*;

import org.junit.Test;
import org.junit.experimental.theories.Theories;
import org.junit.experimental.theories.Theory;
import org.junit.experimental.theories.suppliers.TestedOn;
import org.junit.runner.RunWith;

@RunWith(Theories.class)
public class TheoryTry {

    @Theory
    public void tryTheory(
            @TestedOn(ints = {100, 200, 300}) final int point) {

        assertTrue("should be no error", false);
    }

}

得到的痕迹是：

org.junit.experimental.theories.internal.ParameterizedAssertionError: tryTheory(ints)
    at org.junit.experimental.theories.Theories$TheoryAnchor.reportParameterizedError(Theories.java:192)
    ...
    at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197)

    ...
    at org.junit.experimental.theories.Theories$TheoryAnchor$1$1.evaluate(Theories.java:141)
    ... 20 more

在“故障跟踪”窗口中设置为Filtered，只有三行：

org.junit.experimental.theories.internal.ParameterizedAssertionError: tryTheory(ints)
Caused by: java.lang.AssertionError: should be no error  <---LOOK HERE!
at com.junit.theory.TheoryTry.tryTheory(TheoryTry.java:18)

正如您所看到的，您的信息就在那里。你有不同的东西吗？

Answer 2

升级到JUnit 4.12。他们在那个版本中修复了它，看：https://github.com/junit-team/junit/pull/607

junit理论解决为ParameterizedAssertionError而不是失败
