Introduction

Writing GraphQL Test Cases in Laravel is a bit challenging. Here we will explain how to write the test cases for laravel with graphQL. Writing the test cases for our application is a great way to develop the software with efficiency. There are so many ways to write the test cases like tdd, bdd, ddd develop the software. Before we move further, you must be familiar with the graphql mutation, queries, type, endpoint, schemas. We are using the graphql rebing package here.

Why Do We Write Test Cases?

• Writing the test cases for our application is a good practice when we are building a large scale application. I have covered all the scenarios like adding the new user to check validation, expected outputs, user responses, and identify any potential errors or application difficulties.
• It avoids unwanted errors and bugs in the application during its creation.
• To double check that all functionality code meets quality standards before the installment.

Configure The Write Test Cases

• Laravel supports the testing with in-built phpunit.xml files. These files will set up a system to run the test cases. These files are located at the laravel project root directory.
• In the phpunit.xml file so we create the one new env like .env.testing file in this file connection in another database for testing purposes. Now at this stage we are all set to write the test cases.
• We can use the RefreshDatabase trait inside the class for every time to remove the records from the database and create the new records.
• We are migrating the table using the php artisan migrate –env=testing, so in the testing database all tables are migrated.
