How to Test More, Save Time, and Achieve Better Testing Results:
Software testing is an essential activity in the software development and maintenance life cycles. It is a practice often used to decide and improve software quality.
Development is more systematic nowadays and organizations seek measures of testing completeness and effectiveness to show test completion criteria. Of them all, coverage is considered especially valuable.
Simply put, coverage is “What are we testing and How much are we testing?”
Test coverage helps monitor the quality of testing, and assists testers to create tests that cover areas that are missing or not validated.
Most teams base their coverage calculations on functional requirements alone. It is also fair because first and foremost an application should do what it is supposed to do. If not, its speed or security or ease of use – none of it matters.
However, if dedicated and independent non-functional testing teams are working on performance, security, usability testing, etc., then they will have to track their requirements all the way to execution through test coverage analytics.
What You Will Learn:
Test coverage is often confused with Code Coverage. Even though the underlying principles are the same, they are two different things.
Code Coverage really talks about unit testing practices that have to target all areas of the code at least once and is done by developers.
Test Coverage, on the other hand, is testing every requirement at least once and is obviously a QA team activity.
What really qualifies to be a covered requirement depends on the interpretation of each team.
For example: Some teams call a requirement covered if there is at least one test case against it. Sometimes, it is covered if at least one team member is assigned to it. Or, if all the test cases associated with it are executed.
It is also important as to when to calculate coverage.
If you do this too early in the process, you will see a lot of gaps because things are still incomplete. So it is generally advised to wait until the Last Build i.e. Final Regression Build. This will give a correct coverage of the Tests performed for the given Requirements.
Awareness is everything:
First things first, the QA team must know how much work is involved and where the design tasks are at. This way, they are going to be aware if more tests are to be added. To do this, you could use an RTM as is the typical practice.

Secondly, check resource assignment and test execution process to see if everything is tested in the more effective manner.
A table such as below can be helpful:
|Test Type||Total Cases||Executed Cases||Status||Comments|
|Functional||100||80||50 pass , 30 fail|
|Compatibility||100||50||45 pass, 5 fail|
|Usability||100||100||98 pass, 2 fail|
|Final Regression||100||100||99 pass, 1 fail|
#1) Resource jumbling: Exchange tasks between your team members. This helps improve engagement and prevent knowledge concentration.
#3) Ownership: Make testers accountable and give them a free rein (with monitoring and support of course) for the module/task that they are working on. This helps build responsibility and lets them try creative ways instead of following the beaten down road.
#4) Deadlines: Knowing the release deadlines prior to the commencement of testing phase helps with effective planning
#5) Communication: Stay in touch with the dev and other teams in between release cycles to know what’s going on.
#6) Maintain an RTM: Acts as a good derivative to the Stakeholders or Clients, based on which the release schedule can be confirmed
It is not always true that when you test more, the results are better. In fact, when you test more with no apparent strategy, you probably will end up investing a lot of time.
With a more structured approach, an aim at 100% requirement coverage and effective testing methods, you will not compromise on quality.
We hope the techniques outlined in this article will give you some pointers.
