According to Forrester Research, bringing software testing into the development role (including unit testing) will lower defects and increase code quality. They also noted that even teams that haven’t fully integrated Agile practices can still benefit from developer testing.
According to Forrester, finding bugs early saves time and money later. By engaging in development testing, the initial investment will be paid off with faster releases at a higher quality, with less technical debt.
According to the report, one of the barriers of unit testing has been existing legacy code, which results in slower time-to-market and results in lower code quality. This is, of course, a problem that Typemock Isolator can solve.
Forrester Research recommends educating developers on the importance of developer testing and automating their testing, in order to increase efficiency and save time.
