Test Workflows Examples - Basics

tip

The Schema Reference for Test Workflows describes all available properties and constructs

Running the Image

The Test Workflows spec allows you to provide instructions in setup, steps and after properties.

Syntax

Both setup, steps and after have the same syntax - they are a list of steps. The step is an object that has execution instructions.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-1
spec:
steps:
- run:
image: "curlimages/curl:7.78.0"
args:
- "https://testkube.io"

Running the Image

Use a run instruction that has similar syntax to the native Kubernetes’ container. A command exiting with code > 0 is considered a failure.

Running the Image

Using Shell

Running Shell Commands

For simplicity, you can also run shell commands with the run instruction and the shell property. The script is automatically prepended with set -e, so, by default, it will fail the step on any error.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-2
spec:
steps:
- run:
image: "curlimages/curl:7.78.0"
shell: |
curl https://testkube.io

Alternative Syntax

Alternatively, you can use shell directly as an instruction and a default image will be used.

Using Shell

Fetching the Git Repository

info

Read more about content from Git repositories at Git Repository.

Fetching Data from Git

To fetch data from the Git, use the git property of content. You may provide the address, revision (commit, branch or tag), along with i.e. token.

To avoid fetching all files in mono-repository, you can use paths for sparse checkout.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-3
spec:
content:
git:
uri: "https://github.com/kubeshop/testkube"
revision: "main"
paths:
- "test/cypress/executor-tests/cypress-12"

steps:
- shell: "tree /data/repo"

Mounting

By default, the repository is mounted to /data/repo directory. You can control it with mountPath property though.

Mounting

Fetching a Secured Git Repository

Using a Token from a Secret

You may provide the Git token and username either as plain-text, or via the tokenFrom and usernameFrom clauses that are the same as native Kubernetes env.*.valueFrom.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-4
spec:
content:
git:
uri: "https://github.com/kubeshop/testkube"
tokenFrom:
secretKeyRef:
name: "private-repo-secret-token"
key: "token"

steps:
- shell: "tree /data/repo"

Using Multiple Steps

Running Multiple Steps

To run multiple steps, add another step with the next instructions.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-5
spec:
content:
git:
uri: "https://github.com/kubeshop/testkube"
revision: "main"
paths:
- "test/cypress/executor-tests/cypress-12"

steps:
- name: "Install dependencies"
run:
image: "cypress/included:13.6.4"
workingDir: "/data/repo/test/cypress/executor-tests/cypress-12"
shell: "npm install"
- name: "Run test"
run:
image: "cypress/included:13.6.4"
workingDir: "/data/repo/test/cypress/executor-tests/cypress-12"
shell: "cypress run"

Running Multiple Steps

Container Defaults

Setting Up Defaults

To configure default container settings, you may use the container property. It has a similar syntax to the Kubernetes’ native Container spec.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-6b
spec:
content:
git:
uri: "https://github.com/kubeshop/testkube"
revision: "main"
paths:
- "test/cypress/executor-tests/cypress-12"

container:
image: "cypress/included:13.6.4"
workingDir: "/data/repo/test/cypress/executor-tests/cypress-12"
resources:
requests:
memory: "2Gi"
cpu: 2

steps:
- name: "Install dependencies"
shell: "npm install"
- name: "Run test"
shell: "cypress run"

Notable Nuances

Thanks to the container and run instructions being similar to native Kubernetes’ container specs, you can easily set the required resources for running.

Default Settings

Step Isolation

Nested Steps

You can also pass nested setup steps in the step list.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-7
spec:
steps:
- name: "Run test"
content:
git:
uri: "https://github.com/kubeshop/testkube"
revision: "main"
paths:
- "test/cypress/executor-tests/cypress-12"
container:
image: "cypress/included:13.6.4"
workingDir: "/data/repo/test/cypress/executor-tests/cypress-12"
steps:
- name: "Install dependencies"
shell: "npm install"
- shell: "cypress run"

Content and Defaults

Defaults configured in the step will work similarly to top-level defaults but will be accessible only by the step itself and all steps inside. For example, previous and subsequent steps will not have access to mounted repositories or environment variables.

Step Isolation

Step Orchestration

Optional Steps

You can add optional: true for a step, so that it will not affect the outcome of the orchestration.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-8
spec:
steps:
- name: "Step 1"
optional: true
shell: exit 1
- name: "Step 2"
negative: true
shell: exit 1
- name: "Step 3"
negative: true
shell: exit 0
- name: "Step 4"
shell: echo hello
- name: "Step 5"
condition: always
retry:
count: 3
shell: echo foo; exit 1

Conditional Steps

By default, the next step will run only when the previous steps have succeeded. This can be controlled with the condition property.

As an example, condition: always will cause the step to always be executed, even if the previous step has failed.

Retry Mechanism

It’s possible to automatically retry the step on a failure (or any other condition).

Step Orchestration

Content Files

Provide Static Files

Apart from the Git repository and regular commands, a Test Workflow can use static files directly from the spec - Read More.

These files are mounted from a ConfigMap automatically (unless, instead of content, there is contentFrom used with a similar schema as Kubernetes’ env.\*.valueFrom).

When the path is relative, it will be mounted in the container’s working directory.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-9
spec:
content:
files:
- path: /some/path
content: |
there is some content file
provided.
- path: another-file.txt
content: |
another content
steps:
- workingDir: /foo/bar
shell: |
echo "file 1:"
cat /some/path
echo "file 2:"
cat another-file.txt

Static Files

Artifacts

Saving the Artifacts

Saving the artifacts is as simple as defining the artifacts instruction and providing the file masks to fetch. There is no need to create additional volumes, the artifacts step has access to all the files - Read More.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-10
spec:
content:
git:
uri: "https://github.com/kubeshop/testkube"
paths:
- "test/playwright/executor-tests/playwright-project"

container:
image: "mcr.microsoft.com/playwright:v1.32.3"
workingDir: "/data/repo/test/playwright/executor-tests/playwright-project"
resources:
requests:
memory: "2Gi"
cpu: 2

steps:
- shell: "npm ci"
- shell: "npx playwright test --workers 2 --reporter html"
- condition: always
artifacts:
paths:
- "playwright-report/**/*"

Artifacts

Test Suite Like Runs

Run Dependent Test Workflows or Tests

To run other Test Workflows or Tests, you can use the execute instruction.

You can define the number of concurrent executions with parallelism as well.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-11
spec:
steps:
- execute:
tests:
- name: "example-test"
workflows:
- name: "overview--example-3"
- name: "overview--example-5"
- name: "overview--example-8"

Dependent Tests

Job/Pod Configuration

Configuring the Job

By using the job property, you can configure labels, annotations and execution namespace of the Job. In case of supplying a namespace, you will need to define execution namespaces in your Helm chart values - Read More. It's possible to generate all required RBAC or just manually supply them.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-12
spec:
job:
labels:
job-label: "foobar"
annotations:
this.is.important: false
namespace: "default"

Configuring the Pod

By using the pod property, you can configure labels, annotations, serviceAccountName, imagePullSecrets, volumes, or other properties of a PodSpec.

apiVersion: testworkflows.testkube.io/v1
kind: TestWorkflow
metadata:
name: overview--example-13
spec:
job:
labels:
job-label: "foobar"
pod:
labels:
pod-label: "barfoo"
serviceAccountName: "testkube-api-server"
imagePullSecrets:
- name: "dockerhub-secret"
