Review Comment:
The code below will produce one and only one failure per line and clicking
the stack trace line will take you to the one failure
_assertThat(example).hasSize(1);_
entry count doesn't match ....
```

Any of the three failures will lead you to the one line below and you will
have to break it apart (if it was more complex) to test each condition.
_assertThat(example).containsOnly(entry("1", "ONE"));_
entry doesn't match ....
```
java.lang.AssertionError:
