Consider using A/B testing on your site to determine the impact of response time differences to your customers. If done well, you will determine If performance differences really matter How much they matter Thresholds after which your customers abandon your site

Is it acceptable to re-define boundaries from functional to testable? It depends. If you are testing a value that represent a physical property you can safely limit yourself, although it is a good idea to document it somewhere and double check your assumptions (see the first F16 flights at Dead Sea heights of far below 0) In your case I would invest this ...

Should I create some linkage in my documentation so that the same inputs are avoided across different scripts? Yes, you should create the same to avoid repetition of input data and expected results. Doing this your number of test cases will get reduced to required value, this will save you execution time and test case maintenance effort. Should I ...

Measuring response times in realistic conditions For most organizations, it is not worth the trouble to test your site against the variety of latencies and network speeds you see in production. This is particularly true if you are measuring not just the server response time but the total page render time. The latter depends on a lot of factors, including ...

I do not recommend relying on ISO-9000 for guidance on software quality. ISO-9000 describes a heavy-weight procedure for how companies document all their processes. That is all; it does not address how to create quality. ISO-9000 makes a lot of sense for manufacturing. If you run a factory, and your employees do not have a shared understanding of how ...

Ideally acceptable response time ranges should be specified in SLA or NFR. If they aren't - you need to make an assumption for how long end user will have to wait which may be minutes for i.e. in-house internal application or not more than few seconds for e-commerce websites where user will go away if the site operates slowly or down and will never come ...

This is a situation where a set of test data designed specifically for unusual/rare test scenarios comes in handy. The way I'd deal with your situation is this: Set up two or more extremely high-priced items (preferably at a little under the maximum allowed price for a single item in the system). If your POS system allows quantity limits, ensure the high-...

Having gone through the CMM adaptation I'll point out that it isn't just what is inside the QA process that matters. The QA process needs inputs and outputs and having a formal (written) process means that the inputs and outputs must be standardized as well. Having QA is one of the first level of processes that needs to be developed when improving an ...

I've had the same request a few years ago indeed. The company I am working for decided to set up a dedicated QA dept. After an initial period of research we decided to adopt an international standard, in particular ISO 9001:2008 (we are now TUV certified). The standard is not a step by step guide and sometimes it is really difficult to understand how to ...
