When it comes to the topic of software testing, it can be hard to separate myth from fact. But since businesses rely so heavily on platforms that need testing (websites, apps, etc.), it’s an important part of any software creation process. Let’s break down the five most commonly believed software testing myths, so you have a better idea of how testing fits into development.
Myth #1: Software testing begins post-development
Testing after development (TAD) has an increased likelihood of delaying project delivery. Reversely, testing driven development (TDD) caters to greater efficiency during the project development lifecycle and an excellent customer experience in the end product.
Testing software after development requires the Quality Assurance (QA) team to heavily rely on the construction and design of the developer with little insight into the details of approaches used in the development process. The lack of communication and collaboration between developers and the QA team will likely lead to a decrease in the quality of the user experience.
Testing software throughout the development process offers the QA team the advantage of testing the product incrementally based on all the factors involved. With TDD methods, software expectations are realistically maintained which, in turn, helps developers and testers make appropriate adjustments to each stage of development. Ultimately, TDD methods offer more assurance that projects will meet requirements on time.
Myth #2: Automation tools eliminate the need for manual testing
Manual testing is still necessary for tests that are highly dependent on keen acumen or judgment. Automated testing is the most efficient method to handle repetitive, monotonous testing, but this method cannot yet replace human insight.
The other shortcoming of automated testing is that it requires a human with robust programming skills to write automation code. Writing automation scripts is challenging and requires continuous maintenance and reworking as the product develops. If the approach is incorrect, companies will spend much more than they had anticipated.
Ideally, the best approach is to use both manual and automated testing methods with expert IT talent with the experience necessary to write automation scripts.
Myth #3: Testing leads to increased development costs
There are two options for the level of investment in software testing for companies: spend appropriately before deployment or pay handsomely after development to correct issues found after deployment. Dismantling and re-developing the entire product after deployment can be a big and expensive endeavor, so companies should seek ways to avoid this cost.
There are plenty of budget-friendly options that QA teams can offer businesses, like using open source tools rather than licensed automation tools. This switch is a safe choice because software testing experts should be well-versed in the value of specific open source tools that can provide the same quality results as the expensive licensed tools.
Myth #4: Programming knowledge isn’t required to test software
To test programs well, a complete understanding of the development process is necessary. As it stands, formulating, designing, executing, and evaluating unit test results is a creative process that calls on a sound knowledge of programming.
Software testers create relevant test cases for the different scenarios in a project. The manner in which the tests are carried out is based on a test plan that they have created to ensure that the assessments are handled correctly. When it comes to performing automation or rest API testing, and expert knowledge of the programming language is essential, as well.
Myth #5: Developers can avoid the testing process
Developers’ awareness of the project and the development processes provide valuable insight that the QA team might otherwise overlook.
QA teams provide the added benefit of carrying out testing processes without the detailed knowledge of the developer’s craft. The QA team doesn’t have the same in-depth knowledge of the construction and design processes carried out by the developers, though they typically have a background in programming. Meanwhile, developers have too close of a perspective to their code to assess the product objectively from the consumer. Each team would approach the testing process from a different perspective, which is why both a necessary in the testing process.
Testing software is an integral part of any quality product. The proper understanding of the importance and value of testing can save companies from offering a disappointing user experience, receiving bad press coverage, as well as avoiding significant financial losses.
