[arquillian-issues] [JBoss JIRA] (ARQ-1282) TestNG @DataProvider is fully invoked for each record

TestNG @DataProvider is fully invoked for each record ----------------------------------------------------- Key: ARQ-1282 URL: https://issues.jboss.org/browse/ARQ-1282 Project: Arquillian Issue Type: Bug Components: JBoss AS Containers Affects Versions: 1.0.3.Final Reporter: Karel Cemus h2. Expected behavior TestNG defines @DataProvider annotation to allow single method to perform multiple test cases. Provider method annotated with @DataProvider returns an array of arrays, each containing one test case. These parameters are given to the target method as input parameters. By the definition, the total count of performed test by single method is equal to number of test cases in related data provider. h2. Actual behavior Using TestNG under Arquillian framework makes this functionality buggy. Although the client (maven, IDE, etc.) thinks, that the total number of invoked test is correct, it is not. When we take a look into server's log, we can see that for each single test case it invoked full set of all test cases. It means, that in the end the amount of performed tests is equal to expected count squared. Such behaviour is not only slow but also in some cases it doesn't work and it makes tests to fail. h2. Example {code:java} @DataProvider public Object[][] sumProvider() { return new Object[][]{ new Object[]{ 0, 0, 0 }, new Object[]{ 1, 1, 2 }, new Object[]{ 1, 5, 6 }, new Object[]{ 5, 1, 6 } }; } {code} h3. Expected output in server log {quote} Execution of sum: 0 + 0 = 0 Execution of sum: 1 + 1 = 2 Execution of sum: 1 + 5 = 6 Execution of sum: 5 + 1 = 6 {quote} h3. Actual output {quote} Execution of sum: 0 + 0 = 0 Execution of sum: 1 + 1 = 2 Execution of sum: 1 + 5 = 6 Execution of sum: 5 + 1 = 6 Execution of sum: 0 + 0 = 0 Execution of sum: 1 + 1 = 2 Execution of sum: 1 + 5 = 6 Execution of sum: 5 + 1 = 6 Execution of sum: 0 + 0 = 0 Execution of sum: 1 + 1 = 2 Execution of sum: 1 + 5 = 6 Execution of sum: 5 + 1 = 6 Execution of sum: 0 + 0 = 0 Execution of sum: 1 + 1 = 2 Execution of sum: 1 + 5 = 6 Execution of sum: 5 + 1 = 6 {quote}
