Test icons

The 65 test icons, described

Ablationablation

An ablation — take one part of a system out and see what breaks.

Accessibility testaccessibility-test

A person with arms out — checked for everyone who will use it.

Arrange, act, assertarrange-act-assert

A clipboard with three lines — set it up, do the thing, check the result.

Assert failassert-fail

An X held between brackets — an assertion in the code that failed its check.

Assert passassert-pass

A check held between brackets — an assertion in the code that held true.

Assertion failedassertion-fail

The flask with a cross in it — the check that came out wrong.

Blood testblood-test

The tube with the drop in it.

Canarycanary

A canary release — one instance running the new version so problems show up early.

Chaos testchaos-test

The flask with a bolt in it — something broken on purpose to see what happens.

Continuous integrationci

Continuous integration — every change built and tested automatically as soon as it lands.

Contract testcontract-test

The flask with an equals sign — two sides checked against the same agreement.

Branch coveragecoverage-branch

A bracket pair with a fork in it — both sides of every if, run.

Coverage gapcoverage-gap

A bracket pair with a line and a cross under it — the part no test reaches.

Line coveragecoverage-line

A bracket pair with a line and a check under it — this line ran.

Coverage trendcoverage-trend

A bracket pair with three bars climbing — coverage over time.

Dataset splitdataset-split

A dataset split — most rows to learn from, some held back to be judged on.

End-to-end testend-to-end-test

The flask with a line from wall to wall — the whole path tested as a user would take it.

Evaluationevaluation

Evaluation — measuring how good a model's output is with tests, scores and benchmarks.

Experimentexperiment

An experiment — a flask for trying something and seeing what happens.

Experiment armexperiment-arm

An experiment arm — the branch of users that gets the new thing.

Eye testeye-test

The chart with the letters getting smaller.

Factoryfactory-data

A works with a chimney over a tray — test data made to order, one record at a time.

Factuality testfactuality-test

The flask with a check in it — the model's claims put to the test.

Fakefake-service

A machine frame with a box in it — a working stand-in, simpler than the real thing.

Fault injectionfault-inject

Fault injection — break it yourself before the world does, a chaos test.

Fault injectionfault-injection

The flask with an arrow dropping down its neck — a failure fed in by hand.

Fixturefixture-data

A slab laid in a tray — the data a test starts from, prepared ahead.

Flaky testflaky-test

A flaky test — one that passes and fails on the same code, unreliable and intermittent.

Given, when, thengiven-when-then

A clipboard with a staircase on it — a test told as a story, step by step.

Integration testintegration-test

The flask with two points tied together — pieces tested as they work with each other.

Load testload-test

Axes with a line that ramps up, holds, and ramps down — expected traffic, applied on purpose.

MCP inspectormcp-inspector

The MCP inspector — the tool you debug and test a server with.

MCP server testmcp-server-test

MCP server test — run the server against a pretend client before it goes live.

Mockmock-server

A machine frame with quotation marks in it — a stand-in that expects to be called a certain way.

Mutant killmutant-kill

A crossed-out mutant — a mutation the test suite caught and killed.

Mutation scoremutation-score

A bracket pair with a target in it — how many planted bugs the tests caught.

Needle in a haystackneedle-haystack

One point hidden among many lines — the needle-in-a-haystack test of long-context recall.

Safety probeprobe-safety

A safety probe — a thin question lowered into the model to test what it knows.

Sandbox APIsandbox-api

A play seated in an open box — requests land somewhere real money never moves.

Smoke suitesmoke-suite

The flask with a wisp in it — the handful of tests that say whether anything works at all.

Smoke testsmoke-test

The pipe with a wisp in it — the quick check that the thing runs at all.

Snapshot testsnapshot-test

A window with a lens in it — output captured once and compared against ever after.

Soak testsoak-test

Axes with a line that rises and then holds a long while — steady load kept up for hours.

Spike testspike-test

Axes with one sharp spike — a sudden burst, then nothing.

Spyspy-call

A machine frame with an eye in it — the real thing, with every call recorded.

Stress teststress-test

Axes with a line that climbs off the chart — load pushed past what the system is for.

Stubstub-service

A machine frame with a short bar in it — a stand-in that answers with a fixed value.

Stubstub-tool

A stub — looks like the tool but does nothing, a hollow stand-in for tests.

Test agenttest-agent

A test agent — runs the test suite so nobody has to remember to.

Test data buildertest-data-builder

One block set down in a tray — test data assembled a field at a time.

Test filetest-file

A page with a play button on it — a test file ready to run in the suite.

Focus testtest-focus

The run card with a target — only this test, for now.

Test historytest-history

A clipboard with a clock on it — how a test has done over its last runs.

Test ordertest-order

The run card with three lines — tests run in a fixed sequence.

Test ownertest-owner

A clipboard with a person on it — whose name is on this test when it breaks.

Parallel teststest-parallel

The run card with three bars side by side — tests run at the same time.

Test pyramidtest-pyramid

A clipboard with rows narrowing upward — many unit tests, fewer above.

Test quarantinetest-quarantine

The run card with a box in it — a flaky test set aside so it cannot block the rest.

Test reporttest-report

A clipboard with a check on it — what ran, what passed, what did not.

Test retrytest-retry

The run card with an arrow looping back — a failed test given another go.

Skip testtest-skip

The run card with a skip mark — a test passed over without running.

Test timeouttest-timeout-q

The run card with an hourglass — a test stopped for taking too long.

Test tubetest-tube

The tube standing in its rack.

Unit testunit-test

The flask with one point in it — one small piece tested on its own.

Visual diffvisual-diff

A window split in two with a point each side — two renderings compared pixel by pixel.

In code, each is one import — import { Ablation } from "@iconmind/react/icons/ablation" — and the same name in Vue, Svelte, Solid, Preact, React Native, Astro, Blade and Flutter.
