Using withCapture followed by assertEquals gives MissingInvocation of equals #361
Description
-
Version of JMockit that was used: 1.19, also confirmed in 1.29
-
Description of the problem or enhancement request:
I'm using withCapture() in a Verifications block to make sure a called method uses the expected parameter. Then I'd like to use assertEquals to make sure the captured parameter is what I expect - in my case a LocalDateTime; I haven't been able to reproduce the same issue with other classes.
Instead of the assertEquals telling me what I want to know, though, I get the following:
mockit.internal.MissingInvocation: Missing invocation of: java.time.LocalDateTime#equals(Object)
It's as though JMockit is considering the call to equals() used by assertEquals() part of the code to be verified.
Here's a simplified, self-contained test case demonstrating the bug:
package temp;
import static org.junit.Assert.assertEquals;
import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.util.Date;
import org.junit.Test;
import mockit.Expectations;
import mockit.Mocked;
import mockit.Tested;
import mockit.Verifications;
public class WithCaptureTest {
@Tested
private TestedClass testedInstance;
@Test
public void testWithCaptureBug(@Mocked MockedClass mockedInstance) {
LocalDateTime startOfJanuary = LocalDateTime.of(2016, 1, 1, 0, 0);
LocalDateTime startOfFebruary = LocalDateTime.of(2016, 2, 1, 0, 0);
// @autoformat:off
new Expectations(LocalDateTime.class) {{
LocalDateTime.ofInstant((Instant) any, (ZoneId) any); result = startOfJanuary;
}}; // @autoformat:on
testedInstance.doSomething();
// @autoformat:off
new Verifications() {{
LocalDateTime usedDateTime;
mockedInstance.doSomethingWithDateTime(usedDateTime = withCapture());
assertEquals(usedDateTime, startOfFebruary);
}}; // @autoformat:on
}
public static class TestedClass {
public void doSomething() {
Date date = new Date();
LocalDateTime adjustedDateTime = LocalDateTime.ofInstant(date.toInstant(),
ZoneId.systemDefault()).plusMonths(1);
MockedClass toBeMocked = new MockedClass();
toBeMocked.doSomethingWithDateTime(adjustedDateTime);
}
}
public static class MockedClass {
public void doSomethingWithDateTime(LocalDateTime dateTime) {
// do something...
}
}
}
