The Significance of Test Coverage In Software Testing In this article, we will be covering the concept called as test coverage in software testing. We will see what it is and the advantages and disadvantages associated with it. Apart from software development, software testing courses are also conducted by software training institutes in Pune. You can enroll your name for one. Test coverage measures the amount of testing carried out by a set of tests. Wherever we can tally things and can tell regardless of whether each of those things have been tested by some test, then we can quantify coverage and is termed as test coverage. The essential coverage measure is the place where the 'coverage item' is whatever we have possessed the capacity to count and see whether a test has utilized or exercised this particular item. The formula for determining the coverage is as follows: Coverage= No. of coverage items exercised / Total number of coverage items * 100% There is a risk in utilizing a coverage measure. In any case, 100% coverage does not mean 100% testing is done. Coverage methods measure just a single dimension of a multi-dimensional idea. Two diverse test cases may accomplish the very same coverage, however the input data of one may discover an error that the input data of the other doesn't. Software testing training in Pune would cover both the theoretical and practical aspects of software testing as a part of their course. Advantages of code coverage measurement:
It helps in deciding a quantitative measure of code coverage, which by implication measure the application quality or product. It helps in creation of test cases to increase the amount of coverage. It helps to discover areas of a program not executed by a set of test cases.
Disadvantages of code coverage measurement:
On the off chance that a specific function has not been executed or a function was discarded from the specification, then structure-based methods can't say anything in regards to them it just takes a gander at a structure which is as of now there. One disadvantage of code coverage estimation is that it gauges coverage of what has been composed, i.e. the code itself; it can't say anything in regards to the software that has not been composed.
Why do we perform test coverage? Test coverage is performed mainly for the below mentioned reasons: 1. Test coverage gives us a fair idea as to how much testing is done. This indirectly implies a quality check of the application. 2. If proper test coverage is carried out, then tracking of the changes and impact analysis can be determined. 3. Test coverage enables to find useless test cases which are meaningless to be executed and we can simply discard them. This helps to save time. 4. To discover areas in the stated requirements which are not covered by the test cases and test scenarios. 5. The testing process becomes hassle free and smooth by adopting the risk based testing approach. 6. Traceability between test cases and requirements is possible using this technique. 7. By stating the test coverage, we can create more test cases in order to increase our test coverage. Test coverage best practices in software testing: 1. Use of test management tools is a great practice to have control over all aspects of coverage right from prerequisites, to test cases and defects as well. 2. Quality gate mechanism ought to be appropriate to verify the outcomes. 3. We ought to perform maintenance exercises and cleanup exercises at successive interims of time. 4. We ought to keep up metrics to gauge the test coverage percentage. Thus, we discussed quite a few things about test coverage and related things. Hope that you found it useful.
