Test Suite Advanced – Application Test of Code Blocks
Overview
This application example explains how to use Test Suite Advanced in TIA Portal to perform automated application tests for PLC code blocks. It demonstrates the structure of a test environment and the validation of function blocks using defined test cases.
Application Objective
The objective of this application is to ensure code quality and functional correctness by automatically testing PLC function blocks during development and after project updates.
Application Scope
The application covers the creation of test cases, execution of automated application tests, and evaluation of test results using TIA Portal Test Suite Advanced.
Test Environment Structure
The test environment includes a function block to be tested, a test organisation block, instance data blocks, and test case definitions created using the Test Case Editor.
Test Case Concept
Test cases are created using the Test Case Editor. Each test case consists of multiple test steps, input value definitions, program execution commands, and result validation using assertion commands.
Application Test Execution
The application test is executed automatically by compiling the PLC program, loading it into PLCSIM Advanced, running the defined test cases, and collecting the test results.
Evaluation of Test Results
Test results are displayed as ‘Pass’ or ‘Fail’ in the Inspector window. Detailed results are also stored in log files for traceability and documentation.
