Shift-left Trend and The Effect on Top 3 API Testing Tools

Shift-Left

The attention on API testing has been growing dramatically over the last couple of years, according to Google Trends. Research by Smartbear in 2019 showed that API testers automating more than 50% of their tests, while 45% of the survey participants reported they were responsible for testing APIs. Moreover, API quality is considered as a top priority by more than 75% of organizations across industries. Also, in the World Quality Report 2019-2020, shift-left was mentioned as a trend from now and further while the demand for Integration Testing increased and the mobile testing market.

This article will explain the connection between Shift-left and API testing.

Shift-Left Definition

Shift-left testing is an approach to software testing and system testing in which testing is performed earlier in the life cycle

In the traditional software development model, requirements are placed on the left side of the workflow, and the delivery and testing demand is on the right side. The problem of the traditional model is the negative outcomes for the business such as overdraft, time-consuming, and errors.

By applying Shift-left, software development teams have a more proactive collaboration, especially testers, to ensure all initial ideas are feasible and developed properly. As a result, this approach helps to reduce the time to market of the product while delivering the best possible outcomes.

API Testing in Shift-left Demand:

API testing is so familiar with Testers and QA teams these days. Because of the Application market, more and more test cases have been created to fulfill the requirements of the client and the in-house teams. In the Waterfall model, the testing phase is one of the last steps to be done. With this approach, the Waterfall model turns out to be less efficient when clients’ expectations are unclear and ever-changing. More and more product teams have changed to the Agile process, which enables continuous testing during the software development process.

API testing plays a vital part in the continuous testing process. Testers do not need to wait for the final release, but they can perform crucial tests at earlier stages. API Testing replaced GUI to satisfy the demand for Integration testing.

There are many API Testing tools available in the market. Each tool has its own pros and cons. You can read the list: Best API Testing Tools for 2020 (Updated list) to find out the most suitable one. Among the diverse pool of available tools, the three most outstanding solutions for API testing are Postman, Katalon Studio, and SoapUI. The following part of this article will guide you through a deeper explanation of each tool’s nature.
