Performance testing covers a wide range of different tests.
The benefits can vary whether you test a single URL or a complete user journey through the application.
It might seem obvious, but to add the most value to your load tests you should make them as realistic as reasonably possible.
Quick and unrealistic load tests often prove useless or even counterproductive.
It is often the best way to be overwhelmed with unreliable data.
A realistic load test will allow you to:
Stress all layers of your application. This way you can assess the performance of all your servers and detect bottlenecks.
Pinpoint real bottlenecks. For example a simple load test based on a single URL might point to limitations on your front servers when actually the real users won't experience it because the backend is the first to fail.
Avoid false positives. If you fail to launch realistic tests and encounter a lot of errors, you might stress the CPU of your front servers to handle these errors. The same goes for the network if you don't simulate the load from the right location.
But an AngularJs integration is not that straightforward.
The method explained here can be used to validate the other fields of the credit card.
During my past years as a tester, I often wondered how to get a higher customer satisfaction.
I could go great lengths describing the required skill set and give examples (actually I already did that over here).
When actually the truth is much simpler.
It's not rocket science, it's all about preparations and prerequisites.
