<TL; DR>
Problem: I use Cucumber-JVM and Spring for integration tests. The autwired class in the test step class is not created and is null.
</ TL; DR>
Tests are performed locally, but are not executed on the build server with a null pointer when trying to call a method using a bean.
Stack
- Java 1.8 (local server and build server)
- Maven 3.3.9 (local server and build server)
- Local: Windows 8, Build Server: Ubuntu (cannot understand what it matters)
What i tried
The problem class is annotated by @Component, I tried to remove the @Component annotation and register it in the Spring context - this did not affect.
Setting the Spring log level to DEBUG showed very little and didn't bother anything. For tests that use the Cucumber runner (@RunWith (Cucumber.class)), I see relatively small logs from Spring. Almost no one compared to the unrelated tests that use SpringJunit4Runner.
I wrote a test that uses SpringJunit4Runner instead of the Cucumber runner and auto-fixes the problem class, it worked fine; the class was not null.

This does not work on the build server (normally locally):
import org.junit.runner.RunWith; import cucumber.api.CucumberOptions; import cucumber.api.junit.Cucumber; @RunWith(Cucumber.class) @CucumberOptions(plugin = {"pretty", "html:target/cucumber"}) public class MarketOrderTest { } public class MarketOrderSteps { @Autowired private TestHelper testHelper; @Given("^The order book looks like this before the trade is placed:$") public void setupOrderBook(List<LimitOrder> orders) { System.out.println("TestHelper: " + testHelper); testHelper.setupOrderBook(orders); }
This works fine on the build server and locally, making me believe that the problem lies somewhere with Cucumber / the way I configured it.
@RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration("classpath:*Cucumber.xml") public class SpringTest{ @Autowired private TestHelper testHelper; @Test public void test() { assertNotNull(testHelper); }
