I have notice that i seem to be getting an error:

Does mvn support the data provider?

The new JUnit 5 will no longer be based on Runners but on Extensions. Should this become an incompatible new major version or will the support be added by turning JUnit 4 and 5 into optional dependencies?

Hello

I'm using @RunWith(Arquillian.class) and I'd like to @DataProvide my tests there too.

Since there is no way to say @RunWith twice, how can I use @DataProvider in my Arquillian test class ?

Is there a way to statically initialize or do whatever mojo is needed to mimic the @RunWith(DataProviderRunner.class) ?

@Before public void init() { DataProviderRunner.doTheMagic(). }

The junitparams JUnit runner provides a way to define simple fixed data sets directly in the @Parameters annotation:

@Parameters({ 
            "17, false", 
            "22, true" })
public void personIsAdult(int age, boolean valid) throws Exception {
    assertThat(new Person(age).isAdult(), is(valid));
}

This is very useful for simple, fixed data sets as it does not require in these cases to define an additional method. It would be great if the junit-dataprovider would also supports this feature!

I don't know, if this is already possible, and I just don't know about it, but I find myself often writing wrapper objects, simply providing a reasonable toString for the test parameter (e.g. the input is a Class<?> but I don't want class some.pkg.Foo in the output, but would rather have the simple class name).

Is there any elegant solution for this case? I know I can control the format of the method name, but the parameter always seems to be presented as toString?

Problem IntelliJ Idea is not able to run/debug individual (instances) of parametrized test methods, nor is it possible to directly jump to the definition of the test method by clicking in the JUnit window.

Analysis This is a problem of Idea as the internal implementation is tightly bound the the default parametrized test runner of JUnit.

Proposal May be there is a way to define an API / interface together with JUnit which then can be used by Idea to get exact information about parametrized tests independent of the used approach and/or TestRunner. The other way to fix it: Provide a patch for Idea which treats the DataProviderRunner in the same way like the JUnit runner and hope it finds it way into a future release of Idea.

I know this very unspecific to be a direct JUnit-DataProvider feature request, but the bad integration in Idea is annoying and I'm really interested in getting it fixed at same day.

Hello , would you help to check the issue. I write a sample in https://github.com/weiro-9-w7/junit-data-provider when you DataProviderExternelFileTest testcase, FrameworkMethod get annotation is the other method annotation.

@RunWith(DataProviderRunner.class) public class DataProviderExternelFileTest {

@Test
@UseDataProvider(value = "loadFromExternalFile", location = LoadFromExternalFile.class)
@ExternalFile(format = ExternalFile.Format.JSON, value = "persons.json", clazz=Person.class, isArray=true)
public void should_return_array_when_is_array_is_true(List<Person> person) {
    // Expect:
    assertEquals(person.get(0).getName(), "zhangsan");
    assertEquals(person.get(0).getAge(), 18);
}

@Test
@UseDataProvider(value = "loadFromExternalFile", location = LoadFromExternalFile.class)
@ExternalFile(format = ExternalFile.Format.JSON, value = "person.json", clazz=Person.class)
public void should_return_object_when_is_array_is_false(Person person) {
    // Expect:
    assertEquals(person.getName(), "zhangsan");
    assertEquals(person.getAge(), 18);
}

}

public class LoadFromExternalFile { @DataProvider public static Object[][] loadFromExternalFile(FrameworkMethod testMethod) throws IOException { ExternalFile externalFile = testMethod.getAnnotation(ExternalFile.class); String testDataFile = externalFile.value(); File file = new File(LoadFromExternalFile.class.getResource("/").getPath() + testDataFile); String content = FileUtils.readFileToString(file, "utf8"); if(externalFile.isArray()){ return new Object[][]{{JSON.parseArray(content, externalFile.clazz())}}; }else{ return new Object[][]{{JSON.parseObject(content, externalFile.clazz())}}; } } }

when you run should_return_array_when_is_array_is_true method, but ExternalFile externalFile = testMethod.getAnnotation(ExternalFile.class); externalFile is should_return_object_when_is_array_is_false

Hi there,

in our security tests, there are several methods that look like this:

    @Test
    @DataProvider({
            ENABLED_QUOTATION_AND_STARTED_ENDED_PUBLISHED_RFQ,
            ENABLED_QUOTATION_AND_NOT_STARTED_NOT_ENDED_PUBLISHED_RFQ,
            ENABLED_QUOTATION_AND_STARTED_NOT_ENDED_PUBLISHED_RFQ,
            DISABLED_QUOTATION_AND_STARTED_NOT_ENDED_PUBLISHED_RFQ,
            DISABLED_QUOTATION_AND_NOT_STARTED_NOT_ENDED_PUBLISHED_RFQ,
            ENABLED_QUOTATION_AND_STARTED_NOT_ENDED_NOT_PUBLISHED_RFQ
    })
    public void validate_access_for_buyer_for_not_related_rfq(boolean isQuotationEnabled, boolean hasRfqStarted, boolean hasRfqEnded,
            boolean isPublished)
            throws Exception {
        (...)
    }

As string arrays are not supported in annotations, it would be great if there would be the possibility to extract string based dataproviders into a separate method. Otherwise, a custom string processing is required.

• ( ) Bug report. version: junit4-dataprovider 2.6

my test class likes this

my dataprovider likes this

when I run the getProduct case, the method is not getProduct, why?

Gradle cannot run JUnit @Parameterized tests in parallel, but TestNG has a parallel Boolean parameter on the @DataProvider annotation. Can Gradle run the junit-dataprovider tests in parallel?

At least with java 8 it could be possible to display the name of the test method parameters (instead of the index) in the test name. For example display testDevision[dividend:10, divisor: 2, quotient:5] instead of testDevision[0:10, 1: 2, 2:5] as test name.

Overview

Bug report.

The combination of rerunFailingTestsCount=3 of the maven surefire plugin with the TestNG junit dataprovider did not fail the test, instead it's just marked as flaky, even the count is reached.

There was an issue on the surefire plugin which discusses exactly this problem:
SUREFIRE-1228 (contains a test case as well).

But it seems to me, that the dataprovider is not fully working together with the surefire rerunFailingTestsCount option.

ACTUAL: The maven log ends just flaky (full report in attachment) [WARNING] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Flakes: 1

EXPECTED: The test goes into failure, because even after rerun 3 times the test is not passed.

Versions tested maven-surefire-plugin is latest 3.0.0-M7 com.tngtech.java:junit-dataprovider:1.13.1

I tried even your latest version com.tngtech.junit.dataprovider:junit4-dataprovider:2.9, but still the same maven result: just marked as flaky, but not goes to failure.
