Best practices for shift left testing

[Ehsanuls55]

We have discussed the basic steps you need to follow to implement shift left testing. Here are some pro tips that will make the process even smoother:

Prioritize: Focus on automating high-impact tests that cover critical functions and leave complex tests for manual review. This will prevent excessive automation in the long run.
Foster ownership: Encourage collaboration between developers and testers to give them ownership of the quality of the product. To do:Encourage collaboration between developers and testers so that they take ownership of the quality of the product
Maintain identical test environments: Keep your development, test, and production environments as identical as possible. This reduces the risk of environment-related issues, which can be difficult to identify and correct later in the process.
Use parallel testing: Perform parallel testing, especially automated testing, to speed up the testing process.
Keep test scripts up to date: As the project evolves, periodically update test scripts to reflect new features or changes in requirements.
Left Shift Testing Methodologies
Testing on the left encompasses several methodologies that help integrate testing into the early phases of the software development lifecycle. Here is a closer look at three prominent methods.

Behavior-Driven Development (BDD)
BDD focuses on defining the behavior of the application based on what the user expects when interacting canadian cto cio email list with it. In BDD, tests are written in a natural language format that everyone can understand.

It is a collaborative approach that encourages constant communication between developers, testers, and business stakeholders from the beginning of the project product development cycle .

Example: If you're working on a travel booking app, write a BDD scenario to define the flight search feature's behavior in plain language. This helps ensure that all stakeholders agree on the feature's capabilities before you begin coding.

Test Driven Development (TDD)
TDD is a software development methodology in which tests are written before the actual code. The process follows a cycle:

Writing a test that fails
Write the minimum code necessary to pass the test
Refactor the code
This approach helps you focus on requirements before implementation and reduces the likelihood of defects.

Example: In a financial services project, if you are developing a new transaction processing feature, you would first write a test to verify that the transaction is processed correctly. Only after the test is in place would you write the code to implement that functionality.
