Java testing framework created by Cedric Beust, still actively maintained but effectively a single-lead project

The short version
- Only TestNG has a free tier, so it costs nothing to try first.
- Each has a real cost: mabl tests are stored in a proprietary format and cannot be exported as runnable code, so migrating to Playwright or Cypress later means re authoring every test by hand.; TestNG maintainership is concentrated around creator Cedric Beust rather than a broad team or foundation, which is a real continuity risk compared to JUnit's independent team or Jest's foundation backing.
- They diverge on capability: mabl covers Trainer recorder, TestNG covers Test dependencies.
- Prices and features above were last checked on 1 September 2026.
Where they differ
Only the attributes on which mabl and TestNG actually diverge.
Identical on both: user rating (Not yet rated), category (Testing).

What people use each for
The jobs each tool is most often brought in to do.
mabl
- A QA team of two or three people responsible for regression coverage across a web application released weeklynot TestNG
- An organisation that abandoned a Selenium suite because maintenance consumed more time than manual testing didnot TestNG
- Teams that need accessibility scanning and functional regression reported in the same runnot TestNG
- Product companies where non engineers, such as support or business analysts, are expected to author testsnot TestNG
TestNG
- A Java integration test suite that needs to skip dependent tests automatically when a prerequisite test failsnot mabl
- A team wanting XML-based suite configuration to manage large, grouped test suites without touching code for each runnot mabl
- A project needing native parallel test execution at the class or method level without adding a separate pluginnot mabl
- A Selenium-based UI test suite that uses TestNG as the underlying runner for grouping and parallelisationnot mabl
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
mabl
- Tests are stored in a proprietary format and cannot be exported as runnable code, so migrating to Playwright or Cypress later means re authoring every test by hand.
- Auto healing can mask a genuine defect: if an element is removed and a similar one takes its place, the test adapts and passes when a user facing regression has actually shipped.
- Pricing is not published and is driven by concurrent run capacity, so the cost of shortening a two hour suite to twenty minutes is a renegotiation rather than a configuration change.
- Debugging a failure happens inside a hosted runner you do not control, which makes flakiness caused by test data or environment timing harder to reproduce locally than with a suite you run yourself.
- Native mobile application coverage is thin compared with the browser product, so teams with an iOS or Android app still need a second tool such as Appium or Maestro.
TestNG
- Maintainership is concentrated around creator Cedric Beust rather than a broad team or foundation, which is a real continuity risk compared to JUnit's independent team or Jest's foundation backing.
- It is a smaller ecosystem than JUnit, so fewer third-party integrations, tutorials and Stack Overflow answers exist for edge cases.
- XML-based suite configuration, while powerful, is an extra file and syntax to maintain alongside the codebase, which some teams find adds friction JUnit's more code-centric model avoids.
- There is no commercial support tier or vendor relationship of any kind, unlike JUnit's OpenElements arrangement, so an enterprise wanting a support contract has no route to buy one.
- Release cadence, while active, is slower and less frequent than JUnit 5's, since it depends on a much smaller pool of active maintainers.

Questions people ask
- Is mabl or TestNG better?
- Neither clearly leads. mabl starts at On request and TestNG at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, mabl or TestNG?
- TestNG has a free tier; the other does not. Paid plans start at On request for mabl and Free for TestNG.
- Does mabl or TestNG run on more platforms?
- mabl runs on Web, macOS, Windows, Linux. TestNG runs on Linux, macOS, Windows.
- Can I use TestNG for free?
- Yes. TestNG has a free tier, so you can try it without paying. mabl starts at On request.
- What is mabl best used for?
- mabl is most often used for a qa team of two or three people responsible for regression coverage across a web application released weekly, an organisation that abandoned a selenium suite because maintenance consumed more time than manual testing did, teams that need accessibility scanning and functional regression reported in the same run, product companies where non engineers, such as support or business analysts, are expected to author tests. Of those, a qa team of two or three people responsible for regression coverage across a web application released weekly and an organisation that abandoned a selenium suite because maintenance consumed more time than manual testing did are not what TestNG is typically brought in for.
- What can mabl do that TestNG cannot?
- mabl covers Trainer recorder, Auto healing selectors, API testing, Accessibility checks. TestNG covers Test dependencies, XML suite configuration, Native parallel execution, Data providers.
Answered from the vendors’ own pages
mabl: Can I export mabl tests to Playwright if we leave?
No. You can export documentation of the steps, but not runnable code. Budget for re authoring the suite.
TestNG: Is TestNG still actively maintained in 2026?
Yes, it continues to receive releases in its 7.x line with support for current Java versions, though maintenance is concentrated around a small team led by its creator.
mabl: Does auto healing actually work?
It works often enough to be the reason people buy it, but it cannot be verified from a demo. Trial it against your own application through at least two real releases.
TestNG: What does TestNG offer that JUnit does not?
Native test dependencies, XML-based suite configuration and built-in parallel execution without needing external plugins, all of which JUnit users typically add via separate libraries.
mabl: Is mabl a replacement for unit tests?
No. It covers end to end journeys through a running application. Unit and integration coverage still belongs in your repository.
TestNG: Is there a commercial support option for TestNG?
No, unlike JUnit there is no commercial support arrangement; support is purely community-based through GitHub.
