How to make integration test fail when objectMapper throws exception

Question

I am writing using JUNIT 5 junit-platform-console-standalone library to write integration tests. While reading a JSON object with Jackson, I wish to fail the test if there is any error in reading file.

Tried adding throws IOException to method signature but that doesn;t seem to work.

@Test
void objectMapperTest(){
  // reading file line by line

  objname.foreach(obj -> {
    try{
      Result result = objectMapper.readValue(line,Result.class);
    } catch(IOException e) {
      //How to make the test fail ?  
    }
  });
}

Answer 1

You can use fail()

@Test
void objectMapperTest(){
  // reading file line by line

  objname.foreach(obj -> {
    try{
      Result result = objectMapper.readValue(line,Result.class);
    } catch(IOException e) {
      Assertions.fail("Test failure message");
    }
  });
}
