Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

1. 01

   Limited support for complex Lightning Web Components

   Struggles with components that have intricate dependencies or dynamic content, leading to incomplete test coverage.

2. 02

   Performance issues in large-scale projects

   Test execution can become slow and resource-intensive when dealing with a high number of LWC components.

3. 03

   Documentation lacks depth for advanced use cases

   Advanced features like custom mocking or complex dependency injection are not well-documented, leading to摸索复杂用例的高级功能，如自定义模拟或复杂的依赖注入文档不完善，导致开发人员难以实现这些功能。

4. 04

   Tight coupling with Salesforce ecosystem

   The tool is specifically designed for testing LWC components, limiting its utility outside of the Salesforce environment.

What it does well

• Enables seamless integration with Jest for testing LWC components

• Supports mocking and stubbing of dependencies in tests

• Facilitates unit testing without the need for a full Salesforce environment
