Software testing is key to improving the quality of the software product built by developers. Testing is a vital phase that contains a set of essential actions implemented on a given software to ensure that that the final product that appears at the end of development cycle has uncompromised performance and perfection. With software testing being so significant, it is important to consider that testing process must involve rigorous test cases and firm strategy that is worthwhile.
What testers perform under the test coverage has massive impact on what is received at the end of testing cycle. Efficient test coverage targets all minute points and areas that often go unattended and includes test cases on speed, security and usability of applications. This is why organizations often seek testers that comprehend testing precision and effectiveness.
In order to get applications to do what they are expected to do, testers need to be more visionary and proactive and avoid focusing on limited testing checks.
These are the common mistakes software testers need to avoid about test coverage.
- Lackluster test case practices
To design a set of test cases that verify the quality of a software is a task that demands a lot of preparation and insight. Testers often skip straight to mundane use cases for testing application before identifying scope of testing coverage. A few dull test case practices include:
- Lack of awareness about customer requirements
- Delayed analysis of testable requirements
- Unnecessary steps and irrelevant results
- Lack of uniqueness of tests
- Inflexible testing customs
A Testing specialist should have a thorough understanding of software features, user requirements, and complete familiarity latest industry practices. Moreover, it is necessary to avoid the mistake of writing the test cases after the design phase so that testable requirements can be known in the early phase.
In an effort to make the test design sheet appealing, testers often end up making it all complicated, losing the clarity and simplicity of the job, which is something that needs to be reexamined. Make sure tests are written with relevance and consistency so that each time the test is run, you should expect the same results and not the different one.
- High density of automated tests
To further improve the quality of software during the QA process, development companies drift towards automated testing method which is second most popular trend after agile methodology. However, complete reliance on automated tests could challenge you with the questions of economy, affordability and suitability. Although automation does improve testing coverage, reduce bugs and quickly eliminate regression errors, it is greatly subject to case-sensitive economic proposition. In the software testing industry, automation tools can cost 10 times more than what manual test costs, and it is a colossal mistake trying to automate all tests.
- Mistakes around product coverage
When it comes to covering most critical product elements in testing process, testers must heed to what areas of product need more attention, what areas have already been tested and what remains to be tested.
Product coverage aspect requires software testers to look at the software from unseen angles and run a check to qualify the applications based on how it performs in a specific scenario.
-The common mistake done in this domain is not running the application for analyzing how features exactly perform in unusual circumstances.
For instance, if it is a notepad app, the other aspects to be examined are whether or not the application responds immaculately while simultaneously exploring other apps on the similar underlying environment, and if application crashes when user tries to attempt something untested for. Testers often fail to get applications to behave expectedly with a clean error message or guide content during negative testing.
- Sketchy considerations for risk coverage
Test coverage should necessarily include risk coverage which is something testers sometimes remain shallow about. Risk coverage completes product testing process and it is not acceptable to label the product or software as ‘properly tested’ until you perform all the tests associated with risks.
Being inconsiderate and sketchy about this element of test coverage is the mistake that needs be avoided.
For example, if it is an ecommerce site or application being tested, software testers should be able to think of pressing factors like the amount of traffic accessing the website or application on a special day of discounts and offers. Such use cases of risk coverage could be crucial in determining how application performs on special festive days when the number of interested users is profuse.
- Neglecting the check for code quality
Applications being tested for the quality has to go under the thorough examination for code quality. Neglecting the application code quality is biggest mistake. Testers should not neglect the importance of measuring, documenting and tracking the quality of code.
The best approach for keeping the code quality updated is to use effective metrics some of which are:
- Performance: System should be respond swiftly to execution of any action with certain load . To measure this aspect, testers should run Stress testing and Soak testing.
- Security: The software system should be able to protect the user information against data breaches and cyber attacks. You can measure the Time to resolution taken to resolve vulnerabilities.
- Reliability: This test helps understand how long the system can sustain the performance without failure or crash. The reliability check reduces application downtime. Run Reliability testing to find number of bugs or Load testing and Regressive testing to know how app responds under certain loads and after new updates.
- Ineffective bug reporting
One of the mistakes testers might be making in their test coverage is how to write a report on bug. Finding bugs is as important as reporting them effectively so that identifying the real problem in its exact form becomes easier. If not written cleanly, the bug report may lead to terrible misapprehension.
The bug report document also displays the communication between QA and software developer, and also suggests solutions or changes to be implemented.
Bug testing tools like JIRA make bug reporting easy-to-understand and detailed and helps testers make it clear enough for developers to see and realize what could have gone wrong and where improvements are expected.
With demand for high-quality better performing software applications burgeoning, test coverage for these products need to be intense and complete. However, this does not imply that more tests lead to better results. A viable and thoughtful testing strategy with a structured approach is what it takes for a tester to be successful.
It is possible to avoid all the mentioned mistakes and gain a competitive, unrivalled position if testers choose 100% requirement coverage and focus on delivering high quality each time. Since improved software quality has a huge impact on overall business acquisition and user satisfaction, your product must be handled by a sharp and pragmatic testing company who has unparalleled skills , quality-oriented approach and a powerful QA team.
