- How do I install jenssegers/ab in a Laravel application?
- Run composer require jenssegers/ab, then wire it up: on Laravel versions before 5.5 you register the service provider manually in config/app.php, while 5.5 and later can rely on package auto-discovery. You will likely also want to publish the package config and run any migration it ships for the assignment or goal store. The mechanical setup is quick, but review the shipped files against your own schema before running migrations in a shared environment.
- Which Laravel versions does jenssegers/ab support?
- The only version signal available is that release v0.2.0 added Laravel 5 support, and there is no published compatibility matrix or CI badge for 6, 8, 10, or 11. Treat it as a Laravel 5.x-only package until you read the constraints in composer.json yourself. Check the PHP requirement there too, since Laravel 5-era code often pins an older PHP minor. If your estate runs a modern Laravel version, this package is not a candidate.
- How does sticky variant assignment work and where is it stored?
- It is not documented. Sticky bucketing has to live somewhere: a cookie, the session, the cache, or a database table, and each choice has a different failure mode on cache flush, cookie expiry, or a new device. Read the source to confirm the store, the TTL, and what happens when the stored value disappears. That answer determines whether your experiment results are trustworthy at all.
- Is jenssegers/ab safe to use in production for A/B testing?
- Not without your own due diligence. The package is pre-1.0 with a single-release evidence trail, no published tests or CI, and no stated maintenance or security-disclosure posture, which makes overall technical risk high. The dangerous failure mode is silent: a broken experiment framework keeps running and reports the wrong winner, and roadmap decisions get made on corrupted numbers weeks later. Treat it as a measurement instrument rather than a utility and budget trust accordingly.
- How do I define an experiment and record a conversion with jenssegers/ab?
- The flow is: define an experiment, resolve a variant for a visitor, persist that assignment, and record a conversion when the goal fires. What the source does not spell out is whether a goal records once per visitor or once per request, which directly changes your conversion rate. Read the goal hook in the source and run a controlled spike before trusting any numbers.
- Does jenssegers/ab include statistical significance testing or sample-size calculation?
- No. The package covers only the cheap half of experimentation: assignment and goal hooks. Significance testing, sample-size planning, guardrail metrics, and dashboards remain yours to build or buy regardless of whether you adopt it. Scope that extra work before you commit, because otherwise it dominates the total cost.
- Is jenssegers/ab actively maintained?
- There is no evidence of active maintenance: one visible release, zero stars, zero dependents, and no third-party write-ups or prior community assessment. That is not disqualifying for an internal tool, but it means you would be the first serious adopter and absorb the entire discovery cost. Pin the version and be prepared to fork if you need a fix.
- Is jenssegers/ab a good alternative to LaunchDarkly, Optimizely, or other Laravel A/B testing packages?
- It is a very different shape from hosted platforms such as LaunchDarkly or Optimizely: no external service, no queue workers, no infrastructure footprint, just an application-layer component. That small blast radius is its main virtue, but it also means you get only assignment and goal tracking. Compare it against hand-rolling the same logic or against a maintained package if you are not pinned to Laravel 5.
- How do I test whether jenssegers/ab bucketing is deterministic and evenly distributed?
- There is no published test or CI evidence, so you must write your own verification. At minimum, check that bucketing is deterministic for the same visitor key, that the split is roughly even across a large sample, and that assignment stays sticky across sessions and cache evictions. A short script generating 100,000 synthetic visitors will expose skew or non-determinism quickly.
- Will adopting jenssegers/ab block my Laravel upgrade path?
- It can. Adopting a package whose only framework signal is Laravel 5 support creates an implicit argument for staying on an end-of-life baseline, and a testing dependency quietly becomes the reason a legacy upgrade keeps slipping. Force that trade-off into the open during dependency review rather than letting it die in a ticket. If experimentation matters long term, plan the exit before you plan the integration.
