The short version
- Each has a real cost: Cucumber gherkin's plain-language layer adds a real maintenance burden, keeping feature files, step definitions and implementation code synchronised across a large suite is a known source of drift and duplicated effort.; 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: Cucumber covers Gherkin syntax, TestNG covers Test dependencies.
- Prices and features above were last checked on 1 September 2026.
Where they differ
Only the attributes on which Cucumber and TestNG actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), platforms (Linux, macOS, Windows), user rating (Not yet rated), category (Testing).
What each one covers
Drawn from each product's published feature list. An absence here means we hold no record of it - not that the product lacks it.

What people use each for
The jobs each tool is most often brought in to do.
Cucumber
- A team practising behaviour-driven development that wants shared, readable specifications between product owners and engineersnot TestNG
- An organisation wanting living documentation that stays synchronised with actual test coverage rather than a separate specification documentnot TestNG
- A QA team migrating acceptance tests from a proprietary BDD tool to an open source, community-governed alternativenot TestNG
- A Java, JavaScript or Ruby project needing a mature BDD framework rather than building Gherkin-style parsing from scratchnot TestNG
TestNG
- A Java integration test suite that needs to skip dependent tests automatically when a prerequisite test failsnot Cucumber
- A team wanting XML-based suite configuration to manage large, grouped test suites without touching code for each runnot Cucumber
- A project needing native parallel test execution at the class or method level without adding a separate pluginnot Cucumber
- A Selenium-based UI test suite that uses TestNG as the underlying runner for grouping and parallelisationnot Cucumber
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Cucumber
- Gherkin's plain-language layer adds a real maintenance burden, keeping feature files, step definitions and implementation code synchronised across a large suite is a known source of drift and duplicated effort.
- Ownership has moved twice in under a decade, from independent to SmartBear-owned to independent community ownership again, which should temper confidence in any specific long-range roadmap claim.
- Non-technical stakeholders who are meant to read and write Gherkin scenarios often do not engage with them in practice, leaving the readability benefit unrealised while the maintenance cost remains.
- Step definition reuse across a large feature file set can become tangled, with ambiguous step matching causing hard-to-debug failures as a suite grows.
- As a community-owned project without a corporate backer's support infrastructure, enterprise buyers wanting a formal support contract have no vendor to buy one from, unlike some competing BDD tools still sold commercially.
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.

Which should you pick?
Choose Cucumber if
- You need gherkin syntax.
- You want to start without paying.
- You work on Linux, macOS, Windows.
- You also want step definition binding.

- You need test dependencies.
- You want to start without paying.

- You also want xml suite configuration.
Questions people ask
- Is Cucumber or TestNG better?
- Neither clearly leads. Cucumber starts at Free and TestNG at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Cucumber or TestNG?
- Cucumber starts at Free and TestNG at Free.
- Does Cucumber or TestNG run on more platforms?
- Both run on Linux, macOS, Windows, so platform support will not decide this one for you.
- Can I use Cucumber for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Cucumber best used for?
- Cucumber is most often used for a team practising behaviour-driven development that wants shared, readable specifications between product owners and engineers, an organisation wanting living documentation that stays synchronised with actual test coverage rather than a separate specification document, a qa team migrating acceptance tests from a proprietary bdd tool to an open source, community-governed alternative, a java, javascript or ruby project needing a mature bdd framework rather than building gherkin-style parsing from scratch. Of those, a team practising behaviour-driven development that wants shared, readable specifications between product owners and engineers and an organisation wanting living documentation that stays synchronised with actual test coverage rather than a separate specification document are not what TestNG is typically brought in for.
- What can Cucumber do that TestNG cannot?
- Cucumber covers Gherkin syntax, Step definition binding, Multi-language support, Living documentation. TestNG covers Test dependencies, XML suite configuration, Native parallel execution, Data providers.
Answered from the vendors’ own pages
Cucumber: Is Cucumber owned by SmartBear?
No, not currently. SmartBear acquired Cucumber Ltd in 2019 but the open source project returned to independent community ownership in December 2024.
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.
Cucumber: Is Cucumber free?
Yes, entirely open source with no licence fee across all its language implementations.
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.
Cucumber: Does Cucumber replace Selenium or Appium?
No, Cucumber provides the Gherkin specification layer and step definition binding; the actual browser or mobile automation still needs a driver such as Selenium or Appium underneath.
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.
