1I have a problem with the test. In the test, I am using a mock object of a class. I want to verify that the mock object does not interact with another class. I am using the verifyZeroInteractions() method. The following is the code snippet:2public void test() {3 ClassCastExOnVerifyZeroInteractionsTest mock = mock(ClassCastExOnVerifyZeroInteractionsTest.class);4 verifyZeroInteractions(mock);5}6 when(mock.getArticles()).thenReturn(articles);7public void test() {8 ClassCastExOnVerifyZeroInteractionsTest mock = mock(ClassCastExOnVerifyZeroInteractionsTest.class);9 verifyZeroInteractions(mock);10}11public void test() {12 ClassCastExOnVerifyZeroInteractionsTest mock = mock(ClassCastExOnVerifyZeroInteractionsTest.class);13 verify(mock, times(0)).toString();14}15Missing method call for verify(mock) here:16public void test() {17 ClassCastExOnVerifyZeroInteractionsTest mock = mock(ClassCastExOnVerifyZeroInteractionsTest.class);18 verify(mock, times(0)).toString();19}20public List<SomeObject> getSomeObjects() {21 return Stream.of(1, 2, 3, 4, 5)

If we assume that your job runs in such a small intervals that you really want your test to wait for job to be executed and you just want to test if job is invoked you can use following solution:
Add Awaitility to classpath:
<dependency>
<groupId>org.awaitility</groupId>
<artifactId>awaitility</artifactId>
<version>3.1.0</version>
<scope>test</scope>
</dependency>
Write test similar to:
@RunWith(SpringRunner.class)
@SpringBootTest
public class DemoApplicationTests {
@SpyBean
private MyTask myTask;
@Test
public void jobRuns() {
await().atMost(Duration.FIVE_SECONDS)
.untilAsserted(() -> verify(myTask, times(1)).work());
}
}

Enterprise resource planning (ERP) is a form of business process management software—typically a suite of integrated applications—that assists a company in managing its operations, interpreting data, and automating various back-office processes. The introduction of a new ERP system is analogous to the introduction of a new product into the market. If the product is not handled appropriately, it will fail, resulting in significant losses for the business. Most significantly, the employees’ time, effort, and morale would suffer as a result of the procedure.
In general, software testers have a challenging job. Software testing is frequently the final significant activity undertaken prior to actually delivering a product. Since the terms “software” and “late” are nearly synonymous, it is the testers that frequently catch the ire of the whole business as they try to test the software at the end. It is the testers who are under pressure to finish faster and deem the product “release candidate” before they have had enough opportunity to be comfortable. To make matters worse, if bugs are discovered in the product after it has been released, everyone looks to the testers and says, “Why didn’t you spot those bugs?” The testers did not cause the bugs, but they must bear some of the guilt for the bugs that were disclosed.
Sometimes, in our test code, we need to handle actions that apparently could not be done automatically. For example, some mouse actions such as context click, double click, drag and drop, mouse movements, and some special key down and key up actions. These specific actions could be crucial depending on the project context.
I was once asked at a testing summit, “How do you manage a QA team using scrum?” After some consideration, I realized it would make a good article, so here I am. Understand that the idea behind developing software in a scrum environment is for development teams to self-organize.
