Context

If you name a method with 'And' you are probably missing an extract-and-break method opportunity.

Sample Code

Wrong

calculatePrimeFactorsRemoveDuplicatesAndPrintThem()// Three responsibilities

Right

calculatePrimeFactors();removeDuplicates();printNumbers();// Three diferent methods// We can test them and reuse them

Detection

[X] Semi-Automatic

Some linters can warn us about methods including the term 'and'.

Tags

• Coupling

Conclusion

When making methods, it is very important to play some rubber duck story and tell ourselves if we are making things right.
