co♻e: A unittest framework for CODESYS based systems
Features | Tour | Download | Getting Started | Resources | Acknowledgements
Motivated by absence of a 'good and free' open source IEC61131-3 unit-testing solution.
Developed in Structured-Text for any CODESYS based system, MIT-licensed.
Forked with kind permission by Jakob Sagatowski from TcUnit for TwinCAT3.
Features
| Easy | Powerful | Free |
|---|---|---|
| 1. Download | Increase productivity | Open-Source |
| 2. Install | Stimulate re-usability | MIT-Licensed |
| 3. Reference | Reduce bugs | Well documented |
| 4. Ready! | Cleaner code | Large user community |
| Support for all popular CI/CD platforms | ||
| Part of CForge CI/CD backend |
Compared with TcUnit, co♻e has the following notable differences
Differences
| co♻e | TcUnit | ||
|---|---|---|---|
| All CODESYS based platforms | Beckhoff specific | ||
| By design | Buffered logging to correct log message order | ||
| By design (IDE CLI command line) | Bespoke TcUnitRunner.exe for CI/CD | ||
| By design * | TcUnitRunner.exe generates xUnit reporting file | ||
| Not needed ** | TwinCAT ADS |
* Both TcUnit and co♻e generate this file, but through co♻e mandatorily generated by the PLC
** TwinCAT ADS is bespoke to Beckhoff only

Assistance provided by @aliazzz, @ingo, @i-campbell and @zer0g greatly appreciated.
Without their assistance, porting alone would have taken me several months.
Kudos for helping me out with various tickets and providing invaluable feedback ;-)
