These are the methods that are used in testing the efficacy and functionality of the new software. You find that these methods are majorly used by test managers of software engineers to test how a new software function. Both of them performs the same function, but one will work better for you depending on your preferences. Here are some of the points that we can use to tell the difference between test scripting and explanatory testing methods.
When we start with definition test scripting is a complex set of instructions that testers must follow to see if the desired outcome is achieved. Test scripting is a detailed method and it requires an intensive preparation before the actual test is commenced. For it to uncover all the software errors it should cover all the bases. A lot of work is done when dealing with test scripting.
While explanatory testing relies on the experience and intuition of testers. Besides, these testers are not supplied with the expected outcome in advance. With this, it will be able to identify even the errors that test script writing could not find. Apart from that when comparing their speed, you find that explanatory testing is faster than test scripting in identifying errors. Besides, it does not involve a lot of work.
Another comparison is matters dealing with domain knowledge, this one can be done better by the test scripting. Test scripting will require a lot of documentation and time to analyze the domain and use it in other steps to follow. On the other hand, the explanatory test can work better on unscripted test since it does not require the domain but just the knowledge of the testers.
Apart from that test scripting is not efficient in producing detailed scripts since it is intensive and consumes a lot of time. This involves the production of more detailed and formal record. But on the other hand, explanatory testing is faster and efficient in the production of unscripted tests but majorly it relies on the testers to document their findings.
Another thing is that test scripting formally verify the results against the set specifications. While on explanatory testing, the results are based on the tester’s expectations against the domain knowledge. This makes test scripting able to cover high-risk areas within a minute which can be overlooked by explanatory testing since it depends on testers.
To sum up, when you compare the costs you will find that test explanatory is more cost effective in analyzing software than test scripting which is tiresome and requires a lot of money.
