Do Mock objects get reset for each test?
I don't see a problem here. With the following code using the Mockito API, I managed to do just that :
public class CodeWithPrivateMethod {
public void meaningfulPublicApi() {
if (doTheGamble("Whatever", 1 << 3)) {
throw new RuntimeException("boom");
}
}
private boolean doTheGamble(String whatever, int binary) {
Random random = new Random(System.nanoTime());
boolean gamble = random.nextBoolean();
return gamble;
}
}
And here's the JUnit test :
import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import static org.mockito.Matchers.anyInt;
import static org.mockito.Matchers.anyString;
import static org.powermock.api.mockito.PowerMockito.when;
import static org.powermock.api.support.membermodification.MemberMatcher.method;
@RunWith(PowerMockRunner.class)
@PrepareForTest(CodeWithPrivateMethod.class)
public class CodeWithPrivateMethodTest {
@Test(expected = RuntimeException.class)
public void when_gambling_is_true_then_always_explode() throws Exception {
CodeWithPrivateMethod spy = PowerMockito.spy(new CodeWithPrivateMethod());
when(spy, method(CodeWithPrivateMethod.class, "doTheGamble", String.class, int.class))
.withArguments(anyString(), anyInt())
.thenReturn(true);
spy.meaningfulPublicApi();
}
}

ChatGPT broke all Internet records by going viral in the first week of its launch. A million users in 5 days are unprecedented. A conversational AI that can answer natural language-based questions and create poems, write movie scripts, write social media posts, write descriptive essays, and do tons of amazing things. Our first thought when we got access to the platform was how to use this amazing platform to make the lives of web and mobile app testers easier. And most importantly, how we can use ChatGPT for automated testing.
Traditional software testers must step up if they want to remain relevant in the Agile environment. Agile will most probably continue to be the leading form of the software development process in the coming years.
Mobile application development is on the rise like never before, and it proportionally invites the need to perform thorough testing with the right mobile testing strategies. The strategies majorly involve the usage of various mobile automation testing tools. Mobile testing tools help businesses automate their application testing and cut down the extra cost, time, and chances of human error.
When software developers took years to create and introduce new products to the market is long gone. Users (or consumers) today are more eager to use their favorite applications with the latest bells and whistles. However, users today don’t have the patience to work around bugs, errors, and design flaws. People have less self-control, and if your product or application doesn’t make life easier for users, they’ll leave for a better solution.
