Improve StreamEx coverage

[errandir]

PIT 1.4.3 (default mutators): 100% line and mutation coverage of StreamEx by StreamExTest

[coveralls]

Coverage increased (+0.02%) to 99.079% when pulling 5dc29b3 on errandir:master into c7c7ae7 on amaembo:master.

@amaembo Should I cheat Coveralls to prevent UnorderedCancellableSpliterator coverage decreasing to fulfill it's changes request? Coverage of some lines of this class has highly probabilistic nature. Only injection of synchronization points (which will be enabled only by corresponding tests) could guarantee these lines coverage.

I don't think we should be that obsessed with coverage.

[amaembo]

In general looks good. I will look once more a few days later.

[amaembo]

Thanks. Btw is it possible to integrate Travis build with PITest and get something like a mutation coverage badge or a page where dynamics is displayed in order to keep it at high level?

[errandir]

@amaembo Unfortunately, I haven't found any ready-to-use solution that could provide a pit badge. For now, I think that the most acceptable solution is to somehow extend coveralls plugin to parse pit maven plugin output. But there will be the need to push a separate report (maybe applying some postfix to coveralls' serviceBuildNumber), probably using maven build profiles to allow coveralls plugin process pit and jacoco results separately. Do you have any idea about this?

PS: There is an old open issue on adding pit support to coveralls plugin.

Do you have any idea about this?

Nope. I wanted to add at least a branch support but it seems that coveralls-maven-plugin plugin is abandoned (this PR is more than two years old).

Btw your commits are not attributed to you for some reason. E.g. this commit is not linked to your account. I'm not sure but probably you should check the e-mail settings
