Test Driven Development (TDD) is a testing methodology that helps achieve Speed and Quality with its specifically structured mechanisms. In 2015 we published a blog post on 7 Best Practices for Agile Test Driven Development (TDD)<\/a>. The blog post was hugely appreciated, liked and shared and got over 80,000 hits.<\/p>\n

In this post, we take that further and discuss 5 More Best Practices to derive maximum results from TDD.<\/p>\n

Businesses, small-medium-large, are constantly trying to reduce their costs and at the same time race up to the market. Software Testing approaches and methodologies are being designed increasingly to address both objectives \u2013 Speed and Quality.<\/p>\n

Over a period of time, software testing for business critical software and applications is being increasingly outsourced. Reasons are pretty evident \u2013 leveraging expertise, cutting down time to market, spike up productivity, cost-effectiveness, and improved code quality.<\/p>\n

Building a robust and resilient software\/application is getting more and more critical, as most virtual interfaces offer new customers and opportunities. The software\/application further links and interacts with third party applications that help deliver desired customer experience. For instance, Banking\/Financial applications have numerous offshoots to complete the necessary transactions.<\/p>\n

Most importantly, getting third party expertise on board gives practical insights into the code\u2019s quality and provides an undoubted proof that the code works as intended.<\/span> <\/strong><\/p>\n

While these reasons remain true for outsourcing any type of software testing, it holds true for Test Driven Development (TDD) as well, considering that any form or type of approach has to help serve the business-critical objectives.<\/p>\n

Investments are high and risks are equally high, so getting the best approach that enables agility and speed is critical.<\/p>\n

Why consider Test Driven Development?<\/strong><\/span><\/p>\n

Before we understand various related aspects, let\u2019s get the macro perspective. The core objective behind considering TDD is to build smaller test cycles and bring more agility in the process.<\/p>\n

With TDD you start by scripting the test cases for a new functionality, followed by production code required to pass the test, post that you refactor the code to increase its sustainability.<\/p>\n

It is a technique adopted both for designing the software and testing it. The automated Unit tests are written before the code in this approach, which enables you to get fast confirmation on whether the code behaves as expected.<\/p>\n

TDD is a development process that establishes its finding\/assessments on recurrence of a short development cycle, where the developer writes automated test cases that would further define improvements or new functions and then produce minimum required code to pass the test and ultimately refactor the new code to the required\/improved standards.<\/strong><\/p>\n

\"practices<\/p>\n

The way TDD works, presents its approach and objective too.<\/p>\n

The objective is to have shorter test cycles \u2013 introduce a new test, execute all tests, look out for failures, generate a code, execute the test again, refactor the code basis the results, and then repeat the process.<\/p>\n

Some key reasons for considering TDD are:<\/p>\n
