ecu.test code¶

ecu.test code is a lightweight solution for creating and executing test cases in Python. It is tailored to the needs of software developers and can be used without any prior knowledge of ecu.test. ecu.test code is not a replacement for ecu.test, but rather an alternative way to benefit from the power of ecu.test.

To get up and running quickly, see Getting Started.

Features

• Create and execute test cases directly in your Python environment

• Access ecu.test tools, jobs, and test values

• Record test values to files, leveraging the native recorder feature of the respective tool

• Fast access through config-specific autocompletion

• Seamlessly integrate test results into test.guide

Components

ecu.test code consists of three parts: a Python library, a Visual Studio Code extension, and a pytest plugin.

• The library is the core component of ecu.test code. It activates the capabilities of ecu.test directly inside your Python environment, giving your code access to ecu.test tools, data and automation primitives

• The VS Code extension builds on the foundation of the Library by offering rich autocompletion, inline help and streamlined authoring so you can design, parameterize and run test cases without leaving VS Code. It is an optional add-on.

• The pytest plugin enables seamless integration of test reports into test.guide. It is optional as well.

Limitations

• Only the test steps read, write, execute DIAG-SERVICE and tool jobs are supported

• Only test steps that take or return standard Python data types are supported. Standard Python data types here mean str, int, float, None, as well as list and tuple whose elements are restricted to these types. The test step execute DIAG-SERVICE is an exception to that rule: here, dictionaries with standard Python data types as keys and values are supported for parameters and return values.

• No unit conversion (all values are used as provided)

• Advanced properties such as measuring raster are not supported
