Why AnyAutomation Studio

01

Git-native testing

Test suites are plain-text JSON files next to the project — stage, commit and review them like any other code.
  • Diffable suites
  • Code review for tests
  • No binary black box
02

CI/CD runner

The command-line runner runs headless in GitLab, Jenkins & co. — with JUnit XML for your existing dashboard.
  • JUnit XML & HTML
  • rerun-affected
  • Headless, no TIA UI
03

AI-authored cases

The AI assistant derives test cases and boundary values from the block interface — instead of clicking each case by hand.
  • From the interface
  • Boundary generation
  • Editable in chat
04

Trends & flaky detection

Every run is persisted — compare runs, see regressions and auto-flag unstable tests.
  • Run history & diff
  • Flaky quarantine
  • Trend charts
05

No Ultimate license

SCL unit testing ships with Studio from the Pro tier — no Test Suite Ultimate license needed.
  • Included from Pro
  • Plans in CHF
  • Cancel monthly
06

PLCSIM & real PLC

Test against PLCSIM Advanced or straight against real S7-1200/1500 — over S7 Native or OPC UA.
  • PLCSIM Advanced V3.0+
  • S7 Native & OPC UA
  • Safety prompt

Siemens Test Suite vs. AnyAutomation Studio

An alternative to Siemens Test Suite makes sense when you want to test PLC code like software — versioned, automated and in the pipeline — rather than signing off once. AnyAutomation Studio delivers scriptable SCL unit tests with Git diffs, a CI/CD runner, AI-authored cases and trend reports, without a Test Suite Ultimate license.

What is the difference?

Siemens Test Suite (Advanced) is deeply integrated into TIA Portal and strong for certified acceptance and application-test workflows. AnyAutomation Studio leans on the software-engineering workflow: every suite is a .tia-tests/*.json file next to the project — diffable, reviewable, checked into Git. The tia-test-runner command-line tool runs headless in your pipeline and writes JUnit XML that your existing CI dashboard understands directly.

When to use which?

If you need a certified, TIA-integrated acceptance with formal reporting, Siemens Test Suite stays the reference. If you want to guard PLC logic against regressions continuously, pull tests into code review and CI/CD, and generate cases faster with AI, AnyAutomation Studio is the lightweight alternative. Many teams use both. More detail: SCL unit testing and the unit testing documentation.

Frequently asked questions

What is an alternative to Siemens Test Suite?

An alternative lets you test TIA Portal / PLC code outside the classic Test Suite workflow. AnyAutomation Studio offers scriptable SCL unit tests with Git, CI/CD and AI against PLCSIM Advanced or real S7 hardware.

Do I need a Test Suite Ultimate license?

No. SCL unit testing is included in AnyAutomation Studio from the Pro tier. For PLCSIM Advanced runs you still need a PLCSIM Advanced license from Siemens.

Can I version PLC unit tests in Git?

Yes. Test suites are plain-text JSON files next to your project file and can be staged, committed, diffed and reviewed like any other code.

Does it run in CI/CD?

Yes. The tia-test-runner runs headless in GitLab CI, Jenkins and similar pipelines and produces JUnit XML and HTML reports; --rerun-affected runs only changed suites.

Does it fully replace Siemens Test Suite?

Not for every case. For certified, TIA-integrated acceptance, Siemens Test Suite stays the reference. For versioned, CI-driven unit testing, Studio is the lightweight alternative — many teams combine both.
