YAML-Based Capability Overrides for Selenium Tests on HyperExecute

In Selenium-based testing, capabilities are key-value pairs that define how and where your tests should run—such as browser type, version, OS, console logs, video recording, and more.

Previously, these capabilities were typically defined within the test script. With this new feature, you can now override or inject these directly from your HyperExecute YAML file. This gives you greater flexibility and eliminates the need to modify test scripts every time you change execution parameters.

🚀 Why Use YAML-Based Overrides?

Benefit	Description
No Code Changes Required	Easily change capabilities without modifying your test script.
Reusable & Configurable	Use a single script across different environments with varying YAML files.
Cleaner Test Scripts	Keeps your scripts capability-agnostic and environment-independent.

⚙️ How It Works

• Define a new ltOptions section inside your HyperExecute YAML file.
• Specify any desired capabilities as key-value pairs under ltOptions.
• During test execution, HyperExecute automatically merges these with the final capabilities passed to the Selenium session.

All the capabilities defined under the ltOptions section are fully aligned with LambdaTest's standard capability structure. You can use any capability listed in our LambdaTest Capabilities Generator.

🔑 Key Behavior Rules

Case	Behavior
Capability present in both test script and YAML	The YAML value takes precedence.
Capability present in YAML but not in script	It is automatically added to the session capabilities.
Capability only in script	Used as-is unless overridden in YAML.

📝 Note: This feature is only supported for Selenium-based tests at the moment.
