There is no one-size-fits-all type of software testing that will solve your QA challenges with a single implementation.
Most products will require three to five different types of software testing to reach the highest standards. Thankfully, the overall process is not a tangled mess of test cases. Rather, with the right approach, each type of software testing fits together in both chronological order and as part of a full test cycle: Each is necessary. Each complements the other. And each has a place within your QA process.
