@WieFel Any good idea how to test all the setters?

[WieFel]

@calvintam236 probably the only way is to set some value and use the getters in the same way as you did in the getters tests

@WieFel The problem is what are the expected value of each setter since they all return TinyColor.
For example, https://github.com/TinyCommunity/tinycolor2#lighten
Should it test TinyColor.lighten() == Color.lighten(10)?

[WieFel]

Not sure how to best test this...

Maybe check something like color.lighten().darken() == color.
Not sure whether this assumption actually holds or not.

@WieFel I added the remaining tests by testing every methods independently. Should this sufficient?
Can you take a look if I made any logic error? (I hope not.)
