The challenge here is to figure out where software testing should begin \u2013 from the beginning of the project, parallel to development or at the end of development?<\/p>\n<p>Obviously, this depends on the <strong><a title=\"Software Development Methodology\" href=\"https:\/\/www.verbat.com\/software-development\">software development methodology<\/a><\/strong> adopted by the development company. The methodology also applies to testing. Generally, developers either go for the Agile methodology or the Waterfall approach.<\/p>\n<p>In the Agile approach, testing especially performance testing is started at the beginning of the development process and goes along with the development till the end. The waterfall approach is where testing is done only at the end after development.<\/p>\n<p>Let\u2019s look into both testing approaches in detail.<\/p>\n<h3>Waterfall Methodology\u00a0&#8211; Pros &amp; Cons<\/h3>\n<p>Though Agile has taken over the modern software development sector, many companies still practice the Waterfall model. As mentioned before, performance testing is done only at the end of the development process in the waterfall approach.<\/p>\n<p><span style=\"text-decoration: underline;\">Pros<\/span><\/p>\n<ul>\n<li>Easier to plan the testing and allocate resources since it\u2019s done only at the end of development.<\/li>\n<li>Typically uses test environments that share many similarities with the production environment.<\/li>\n<li>Testing can focus on specific characteristics of the product based on priority.<\/li>\n<\/ul>\n<p><span style=\"text-decoration: underline;\">Cons<\/span><\/p>\n<ul>\n<li>Testing environment being similar to that of production makes it challenging to procure infrastructure exclusively for testing purposes.<\/li>\n<li>Might demand architectural changes toward the end of development as testing also occurs at the end, which would in turn increase cost.<\/li>\n<li>The team and the client would have to wait till the end to get assurance on performance which is also risky. Should the team identify major bugs in the system, they\u2019d have to fix it before release which could essentially lead to failure in release by the deadline.<\/li>\n<\/ul>\n<h3>Agile Methodology \u2013 Pros &amp; Cons<\/h3>\n<p>There is a reason why <strong><a title=\"Agile Development Services\" href=\"https:\/\/www.verbat.com\/services\/agile-software-development-services-company\">Agile development services<\/a><\/strong> enjoy great demand today. However, along with all its benefits, Agile does come with a fair share of challenges. In an Agile approach, testing begins right from the beginning of development with unit testing. Implementing continuous integration into development makes the entire process much faster, transforming simple performance testing to \u2018performance engineering\u2019.<\/p>\n<p><span style=\"text-decoration: underline;\">Pros<\/span><\/p>\n<ul>\n<li>Reduced risk<\/li>\n<li>Early, constant feedback.<\/li>\n<li>Continuous improvement, where testing finds bugs that are rectified in successive sprints.<\/li>\n<li>Facilitates continuous integration.<\/li>\n<\/ul>\n<p><span style=\"text-decoration: underline;\">Cons<\/span><\/p>\n<ul>\n<li>Requires more effort in maintaining scripts and handling automation.<\/li>\n<li>Automating less or more can lead to complications. The best practice is to automate critical test cases at the GUI level.<\/li>\n<li>More testing effort where the team has to test components individually, and then test them working together to achieve optimal results.<\/li>\n<\/ul>\n<h3>Making the choice<\/h3>\n<p>Choosing the development approach requires us to consider the desired outcome and the project\u2019s deadline. There are other important factors as well including the people who are going to work on the project, the technology that\u2019s going to be leveraged, the development and testing tools that would be used, the processes involved etc.<\/p>\n<h3>Testing for Waterfall &amp; Agile<\/h3>\n<p>Testing processes generally include test design, test automation, test execution, and test measurement.<\/p>\n<p><span style=\"text-decoration: underline;\">For Waterfall<\/span><\/p>\n<p>Software testing in waterfall development requires the tester to execute a load simulation at the end. With the simulation, the tester can:<\/p>\n<ul>\n<li>Verify whether existing system supports a certain load<\/li>\n<li>Give proof to the client as to how the system meets a predetermined standard for performance.<\/li>\n<li>Check if the application requires some tweaking for the context where it will run.<\/li>\n<\/ul>\n<p><span style=\"text-decoration: underline;\">For Agile<\/span><\/p>\n<p>Performance testing is essentially \u2018performance engineering\u2019 in Agile, which reduces both cost and risks. It allows the team to understand the concept of performance engineering while executing it throughout the development cycle.<\/p>\n<h3>Conclusion<\/h3>\n<p>At the end of the day, we can\u2019t choose one testing approach over the other though this isn\u2019t the case when it comes to development. Early performance testing and load simulation for acceptance testing are both important, and needs to be part of the testing strategy depending on how far the development has progressed.<\/p>\n<p>This blog explores the two most commonly practiced testing approaches\u00a0&#8211; Waterfall and Agile, and where performance testing fits in both.<\/p>\n<p>Making the choice between Waterfall and Agile performance testing is not easy. This blog shares some insights on both approaches and where performance testing fits in them.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>While developing software, every team will have to determine that point of time where performance testing of the product will benefit them most.
