Before releasing a product, it is important to perform end-to-end testing, which involves analysing it from different perspectives. One needs to majorly focus on Test Driven Development (TDD) and Behaviour Driven Development (BDD) throughout this phase of the agile software development life cycle. TDD allows developers to check the quality of their code. It enables them to identify whether all of the features and components of an application, website, or other software are synchronised in the manner that is expected. On the other side, BDD enables developers to code features after first gaining knowledge of the requirements of users. When it comes to software development, using best practises without utilising TDD and BDD can put the project in jeopardy. Similarly, the tools and technology stack that your engineers use to create software should be appropriate. For instance, to create the product, your technology provider should use the latest tools and technology for proper testing.
