 You can configure the environment variables necessary to build the component using the **Build Configurations Editor** on the component **Build** page. 
 
-!!! info
-    The capability to configure build-time environment variables is not available for components created using **Ballerina** or **WSO2 MI** build presets.
-
 During the build process, the build-time environment variables and their values are passed to the build preset. Therefore, you can configure both build preset-specific environment variables and those required for the component build.
 
 For example, if you want to override the Maven command of the **Java** build presets, you can use `GOOGLE_MAVEN_BUILD_ARGS` as the environment key and `clean install` as the value.

 Choreo allows you to integrate unit tests into the build pipeline, enabling code validation before deployment. This ensures early testing of code changes, reducing the risk of defects in production.

-## How it works
+## Write tests
 
-### Step 1: Write tests
+You can create unit tests in your source code using standard testing libraries. For step-by-step instructions on creating unit tests for WSO2 Micro Integrator projects, see [Creating a Unit Test Suite](https://mi.docs.wso2.com/en/latest/develop/creating-unit-test-suite/). For step-by-step instructions on writing unit tests for Ballerina projects, see [Test Ballerina Code](https://ballerina.io/learn/test-ballerina-code/structure-tests/).

+Once you have written your unit tests, commit them to your source code repository.
 
-### Step 2: Enable unit tests
+## Enable unit tests
+
+To enable unit tests in the build pipeline for a component with unit tests in its source code, follow these steps:
 
 1. Sign in to the [Choreo Console](https://console.choreo.dev/).
-2. In the **Component Listing** pane, click the component for which you want to enable unit tests.

 4. On the **Build** page, click to edit **Build Configurations**.
 5. Turn on the **Unit Test** toggle.
 6. Click **Save**.
 
-### Step 3: Trigger a new build

 ## View failed unit tests
 
-If a unit test fails during the build, you can view its detailed logs for troubleshooting. Click **View Details** corresponding to the failed build, then expand the failed unit test step to view the logs.
+If a unit test fails during the build, Choreo will stop the build to prevent faulty code from being deployed. To troubleshoot, click **View Details** for the failed build and expand the failed unit test step to review the test output logs.
