I have a line in my test that currently looks like:


I would like to modify it to check if the parameter contains both "apple" and "banana". How would I go about this?

Just use Mockito.matches(String), for example:


org.mockito.ArgumentMatchers.contains java code examples, ArgumentMatchers.contains java code examples, Learn how to use contains in ArgumentMatchers, Get the top 20 code snippets using EXECUTE_ACTION); verify(this.loader, Mockito.times(2)).unassignExecutor(-1); String argument that contains the given substring. Object argument that implements the given class. Using Mockito is not just a matter of adding another dependency. It requires changing how you think about your unit tests while removing a lot of boilerplate. In this article, we'll cover multiple mock interfaces, listening invocations, matchers, and argument captors, and see firsthand how Mockito makes your tes

I think the easiest solution is to call the verify() multiple times:

verify(emailService).sendHtmlMail(anyString(), eq(REPORT_TITLE), contains("Client response31"));
verify(emailService).sendHtmlMail(anyString(), eq(REPORT_TITLE), contains("Client response40"));
verify(emailService, never()).sendHtmlMail(anyString(), anyString(), contains("Client response30"));

ArgumentMatchers (Mockito 2.5.3 API), Since Mockito any(Class) and anyInt family matchers perform a type check, thus they won't match null arguments. Instead stubbing using anyBoolean() argument matcher when(mock. String argument that contains the given substring. thenReturn(100); //prints 100 System.out.println(, 2)); // also prints 100� The following is the test that mocks the dependency using Mockito: public class customer which is passed in as a parameter to the mock method. The Two Ways of Testing Void Methods With

Since Java 8 and Mockito 2.1.0, it is possible to use Streams as follows:

    Mockito.argThat(s -> s.contains("apple") && s.contains("banana"))

thus improving readability

A Unit Tester's Guide to Mockito, With Mockito, you create a mock, tell Mockito what to do when specific We'll include both ways of stubbing in our examples. It has a single method with a parameter of type InvocationOnMock . null for strings and arrays, the mocks created with RETURNS_MOCKS return empty strings and empty arrays, respectively. 29 How to check if a parameter contains two substrings using Mockito? 29 Who are Mike, Esther, and Sheila?

Maybe this is not relevant anymore but I found another way to do it, following Torsten answer and this other answer. In my case I used Hamcrest Matchers


Check If a String Contains a Substring, Explore various ways to search for a substring in a String with performance benchmarks. 2. String.indexOf. Let's first try using the String.indexOf method. An interesting point is that contains internally calls indexOf to know if a We'll search in which position “eiusmod” is present in the message variable. Mockito Argument Matchers – any() Sometimes we want to mock the behavior for any argument of the given type, in that case, we can use Mockito argument matchers. Mockito argument methods are defined in org.mockito.ArgumentMatchers class as static methods.

Java: Check if String Contains a Substring, Checking if a String contains a substring is a common task. In this article, we'll be exploring the core Java approach and the Apache Commons approach to� Mockito offers two equivalent ways of mocking: Using static methods and; Using @Mock annotations. All the examples in this article use static methods. Feel free to use annotations instead, but make sure that you agree on a single solution with the rest of your team, so that unit tests are written in a common format.

Using matchers, Checking equality with matchers; Checking size and length; Checking strings If you ever do want to verify that two arrays are actually the same object (have the same Although the implicit parameter required for the contain syntax is of type � This is where Mockito Spies come into the picture. If you’d like to learn more about using Mockito Spies, check out this post. Summary. Mocking in unit testing is extensively used in Enterprise Application Development with Spring. By using Mockito, you can replace the @Autowired components in the class you want to test with mock objects. You

Matchers, the different ways of checking the equality of values; to use the matchers for the most common ignoreCase, check if 2 strings are equal regardless of casing. This tutorial illustrates various uses of the standard static mock methods of the Mockito API. As with other articles focused on the Mockito framework (like Mockito Verify or Mockito When/Then), the MyList class shown below will be used as the collaborator to be mocked in test cases:

  • Check this article Argument matching with Mockito for working example.
  • I do not agree with your answer because it could be different method calls and you could not know it for sure. FYI I did not vote your answer down.
  • While this code may answer the question, providing additional context regarding how and why it solves the problem would improve the answer's long-term value.
  • Thanks - this looks like a useful and more up-to-date answer. I asked this question 9 years ago, and so it might be worth mentioning the versions of Java (e.g. Java 8 streams) and/or Mockito (the docs mention this interface changed in 2.1.0:… ).
  • Since Java 9 it could be written even shorter: Mockito.argThat(s -> List.of("apple", "banana").contains(s)).
