We currently place 2 mutations for >= (<=
and >
). The <=
mutation already forces the programmer to write a test for the value higher than 18.
As far as I know we tackle all edge cases with these 2 mutations. But if we could simplify by just placing 1 mutation that would improve our performance. We could look into, if this mutation covers the same edge cases.
Example:
Code tested: public static bool Is18OrOlder(int age) { return age >= 18; }
Existing tests: [Fact] public void Minor_Test() { Assert.False(AgeControl.Is18OrOlder(0)); }
[Fact] public void Equal_Test() { Assert.True(AgeControl.Is18OrOlder(18)); }
Both of them pass green when >= is replaced by == , the mutation into == should force the programmer to write a test for higher value than 18 in our example
