从Java中的循环创建多个单元测试

问题描述

我正在为我的(小型)程序编写单元测试，并且在大约30个不同的文件中指定了测试用例.
为了测试它，我需要做的是遍历所有文件，解析它们并执行所需内容的循环.

I'm writing unit tests for my (small) program, and the test cases are specified in around 30 different files.
To test it, all I need is a loop that goes over all the files, parse them, and execute what's needed.

问题在于，在这种情况下，我的所有测试都将被视为一个，因为所有测试均使用@Test表示法在同一函数中.
是否可以以某种方式拆分它，而不必为每个测试文件都具有单独的功能?

The problem is that in that case, all of my tests will be considered as one, since it's all in the same function with the @Test notation.
Is it possible to split it somehow without having to have a separate function for each test file?

将所有测试作为一个测试用例的问题在于，我看不到哪个测试用例未能通过该过程.如果其中一个失败，则其余的失败(我将使1个测试失败，而不是5/30失败)

The problem with all the tests as one test case, is that I can't see which test case fail the process; and if one fails it fail the rest (I'll get 1 test failed instead of 5/30 failed)

我目前正在使用JUnit(4.12)，但我没有义务继续使用它，因此，如果有更好的解决方案，我可以切换框架.

I'm currently using JUnit (4.12), but I'm not obligated to keep using it, so I can switch framework if there's a better solution.

谢谢！

示例:

public class MyTests {
    @Test
    public void testFromFiles {
        // loop through all the files
    }
}

output: 1 test run successfully

更新:选定的答案对我来说非常有效，我还为JUnit 5(而不是4)添加了另一个解决方案，以防它对某人有所帮助.

Update: The selected answer worked great for me, and I added another solution with JUnit 5 (instead of 4), in case it will help someone.

推荐答案

尝试这种方式:

@RunWith(Parameterized.class)
public class EdiTest {

    @SuppressWarnings("WeakerAccess")
    @Parameterized.Parameter(value = 0)
    public String model;

    @SuppressWarnings("WeakerAccess")
    @Parameterized.Parameter(value = 1)
    public String filename;

    @Parameterized.Parameters(name = "{index}: testEDI({0}, {1})")
    public static Collection<Object[]> data() {
        return Arrays.asList(new Object[][]{
                {"753", "edi753_A.edi"},
                {"753", "edi753_B.edi"},
                {"754", "edi754.edi"},
                {"810", "edi810-withTax.edi"},
                {"810", "edi810-withoutTax.edi"},
        });
    }

    @Before
    public void setUpContext() throws Exception {
        TestContextManager testContextManager = new TestContextManager(getClass());
        testContextManager.prepareTestInstance(this);
    }

    @Test
    public void testEDI() throws IOException {
        String edi = IOUtils.toString(ClassLoader.getSystemResource(filename));
        EdiConverter driver = ediConverterProvider.getConverter(model);

        // your test code here
    }

}
