--------------------------------------
Summary: Power assert with unique() gives confusing output (was: Power
assert gives confusing output)
> Power assert with unique() gives confusing output
> -------------------------------------------------
>
> Key: GROOVY-5345
> URL: https://issues.apache.org/jira/browse/GROOVY-5345
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 1.8.6
> Environment: Groovy Shell (1.8.6, JVM: 1.7.0_147-icedtea)
> Ubuntu 11.11
> Reporter: Volodymyr Sobotovych
> Priority: Minor
> Attachments: power_assert.groovy
>
>
> Here's a code with a wrong assertion:
> {code}
> def x = [1, 1, 1]
> assert x.unique() == [2]
> {code}
> And here's the output I get:
> {noformat}
> wheleph@laptop:~/groovy$ groovy power_assert.groovy
> Caught: Assertion failed:
> assert x.unique() == [2]
> | | |
> | [1] false
> [1]
> Assertion failed:
> assert x.unique() == [2]
> | | |
> | [1] false
> [1]
> at power_assert.run(power_assert.groovy:2)
> {noformat}
> While it does state that the assertion failed, the output is confusing
> because {{x}} was {{[1, 1, 1]}} at the start of {{x.unique()}}. I guess this
> behavior is caused by the fact that {{unique()}} changes the list itself
> rather than returns a new instance.
