If you are interested in improving and maintaining the uality of your code this book should be on your reading list It is not the kind of book you read once and forget about it When you are doing refactoring it s always recommended to come back and check the categories explained in it What I really enjoyed is that it confirmed some of the ideas I already had about software development On the first hand you should have a robust test suite in order to be certain that refactoring didn t change the behavior of the software Further you should never start writing new features on top of code that looks like it needs refactoring First refactor and then write new code Lastly refactoring should not stop the progress of your project but be continuously integrated with the development phaseThe book was written a while ago and some comments regarding the effectiveness of refactoring tools are a little bit outdated but since it is not concerned with providing a catalogue of this kind of tools this aspect is not so relevant Etapy zmiany w terapii uzależnień Wybór i planowanie interwencji maintaining the uality of your code this book should be on your reading list It is not the kind of book you read once and forget about it When you are doing refactoring it s always recommended to come back and check the categories explained in it What I really enjoyed is that it confirmed some of the ideas I already had about software development On the first hand you should have a robust test suite in order to be certain that refactoring didn t change the behavior of the software Further you should never start writing new features on top of code that looks like it needs refactoring First refactor and then write new code Lastly refactoring should not stop the progress of your project but be continuously integrated with the development phaseThe book was written a while ago and some comments regarding the effectiveness of refactoring tools are a little bit outdated but since it is not concerned with providing a catalogue of this kind of tools this aspect is not so relevant
