Today, manual and automated testing are playing a significant role in any tech-driven company. Whether it’s a mobile or web application or website, code verification is crucial. Proper planning and knowing not only what kind of testing to perform but when to perform it helps save time and make the best use of a client’s budget.
Both testing methods have their pros and cons and we will review them below.
Let’s start with identifying the definition of manual and automated testing. From Wikipedia:
Which of these two kinds of testing does Ventive recommend?
While manual testing performed by QA engineers is the easiest way to test an application, automated testing has its place too. Automated testing tools maximize test coverage by leveraging software to monitor the test cases and compare the expected versus actual results. It's perfect for frequently repeated scenarios.
However, it is important to note that there must be manual testing in order to facilitate effective automated testing. Before writing the script for automated execution, each scenario needs to be tested manually and documented into the test case. Manual testing requires a lot of effort, but it is vital in order to understand if automation is even possible.
100% automation is not possible.
It may seem like manual testing is easy, but it’s not that simple. Verifying the maximum possible number of execution paths using the minimum number of test cases requires strong analytical skills.
Some testing types, such as regression testing, can be time-consuming if performed manually. Additionally, manual testing is not an efficient way of performing load or stress testing. In such cases, automation can help save time and effort.
By creating automated scripts, these types of tasks can be executed at any moment to improve both speed and accuracy. Thus, if there is a need for frequently repeated runs of test cases, the importance of automation to simplify project maintenance and reduce its cost is difficult to overstate. After all, even small patches and code changes can cause new bugs.
When considering automation, you must consider what, when, and how to perform these tests. Choosing the right automation tools will, to a large extent, determine the success of automated testing. One of the best practices is to avoid automating sections of code that can change frequently.
Avoid automating sections of code that can change frequently.
Each code change will require changes in automated scripts, otherwise the execution will fail.
A combination of manual and automated testing is often used, and the level of automation will depend both on the type of the project and on the production processes of the company.
As you scale up the development process for users, your application may behave differently at 100 users than it does at 10,000 users. But figuring out the bugs at 100 users will help you get to the point where you can build out the product to serve 10x the users. Depending on where you're at in the app development process, both manual and automated QA testing will be necessary to deliver the final finished product.
