There exists no perfect method of testing a software. The modern times we live in demand for contemporary testing strategies. Which method to apply for testing a software depends a lot upon the functionality that needs to be tested!

? An example from front-end point of view -

If you want to test the front-end of your website across different browsers as rendering of web elements is not the same on all browsers. Then you will need to perform Cross Browser Testing to ensure that your website or web app works seamlessly across all major browsers.

? An example from back-end point of view -

If you offering a black friday deal to every visitor on your website then you will have to check whether your server will be able to handle the additional load brought by the excessive traffic. This is where you need to perform load testing, functional testing etc. This is highly relevant if you are hosting a B2C service like e-commerce web store and soon.

? An example from development pipeline -

A developer needs to perform unit testing before migrating a change to a staging environment or QA environment. A software tester would then perform various type of modern day testing approaches to ensure an outage proof release. This is where the relevancy of different types of modern testing steps into play.

  • Accessibility Testing – To make sure your software is accessible to all, including people with special disabilities.

  • Usability Testing – Testing of a website for its usability concerning user satisfaction.

  • Exploratory Testing – Testing approach that includes simultaneous learning, test designing and test execution.

  • Regression Testing – Testing the whole application after any new change has been made. The idea here is to check that the new change is not disrupting any of the pre-existing functionality. With digital discovery being more mobile centric it is crucial that you be ready for mobile web pages with regression testing.

  • Cross Browser Testing – Testing to ensure that your webapp is operable through different browsers, across various devices with different screen sizes.

It is vital that you stick to different contemporary testing strategies.

An example from execution point of view:

In a project where the content is large and the testing phase runs for quite a long time, automation testing is the perfect choice since

  • It reduces the number of resources required.

  • Multiple type of similar test case scenarios can be executed simultaneously with a single script.

  • For a large project, the estimated budget is sufficient enough to afford the set up and maintenance of an automated testing tool.

However, in small projects where the testing phase runs for only a few weeks, Manual testing is more preferable since

  • Resources do not have enough time to get trained in the tools and start testing.

  • Maintenance and installation is time consuming and costly.

  • There is less need of simultaneous execution of multiple test cases of similar nature.

Since you are asking which method is best, I know automation is the need of the hour and sounds pretty cool and dominant but let me clear a few myths related to automation testing.

  • You can deploy a 100% fully automated testing! – These scripts are written by human, there is only a limit to how far sighted one can be! Doesn’t matter how tremendous testers are working under your firm, they can’t predict all the possible test cases required to call a software 100% bug free.

  • Just Record and Playback. That is all there is to it! – Many automation tool vendors advertise mentioning us to just record and playback for automating the testing process through their tool. But that isn’t true! The real automation starts after the playback once you have the idea regarding the test script being generated by the tool.

  • Automation Testing is going to substitute Manual Testing! – Since a 100% automation is an impossibility, manual testing will always be irreplaceable. The point of automation testing is to allow testers the time to look for loopholes in the system manually and think of better test cases. Manual testing can never be trivialized and here are some reasons for which manual testing is still prevailing.

With all that said, you need to remember that testing is a process of continuous evaluation and learning. With the speed at which the software world in accelerating, you can’t afford to rely all your testing needs on just a single method. There is no best method but there do exists the efficient ones.
