Test
based syntax¶
The Test
based syntax is more verbose than the manifests based syntax but offers more flexibility and features:
- Does not rely on file naming conventions for operations ordering
- Allows to easily reuse files accross multiple tests
- Offers the flexibility to provide additional configuration at the test, step and operation level
- Supports all operations and collectors
The Test
resource¶
A Test
resource, like any Kubernetes resource has an apiVersion
, kind
and metadata
section.
It also comes with a spec
section used to declaratively represent the steps of a test and other configuration elements belonging to the test being defined.
Reference documentation
The full structure of the Test
resource is documented here.
Test steps¶
A Test
is mostly made of test steps. Test steps are detailed in a dedicated documentation.
Example¶
chainsaw-test.yaml¶
The manifest below contains a Test
in a file called chainsaw-test.yaml
.
Chainsaw will load the Test
and steps defined in its spec
section.
The Test
uses a custom timeouts
for the whole test. Note that timeouts
could have been overridden in specific steps if needed.
apiVersion: chainsaw.kyverno.io/v1alpha1
kind: Test
metadata:
name: test-name
spec:
skip: false
concurrent: false
skipDelete: false
# these timeouts are applied per operation
timeouts:
apply: 10s
assert: 10s
error: 10s
steps:
# first step
# apply a configmap to the cluster
# the path to the configmap is relative to the folder
# containing the test, hence allow reusing manifests
# across multiple tests
- try:
- apply:
file: ../resources/configmap.yaml
# second step
# execute assert statements against existing resources
# in the cluster
- try:
- assert:
file: ../resources/configmap-assert.yaml
# third step
# execute error statements against existing resources
# in the cluster
- try:
- error:
file: ../resources/configmap-error.yaml
Specifying a Custom Test File¶
If you have your test defined in a different file, you can specify it when running Chainsaw:
$ chainsaw test --test-dir . --test-file=<custom-test-file-name>.yaml
Raw Resource Support¶
Chainsaw now includes the raw resource feature, allowing direct specification of Kubernetes resources within the test definitions.
This feature offers a more streamlined approach for defining resources, especially useful for simpler test scenarios or for cases where resource definitions need to be reused or slightly modified across different tests.
Example Raw Resource¶
apiVersion: chainsaw.kyverno.io/v1alpha1
kind: Test
metadata:
name: test-name
spec:
skip: false
concurrent: false
skipDelete: false
timeouts:
apply: 10s
assert: 10s
error: 10s
steps:
# first step applies a configmap directly to the cluster
- try:
- apply:
resource:
apiVersion: v1
kind: ConfigMap
metadata:
name: chainsaw-quick-start
data:
foo: bar
# second step executes assert statements against existing resources
- try:
- assert:
file: ../resources/configmap-assert.yaml
# third step executes error statements against existing resources
- try:
- error:
file: ../resources/configmap-error.yaml
URL Support for File References¶
Chainsaw has support for URLs in file references for assert, apply, error and similar operations.
This feature enhances the reach of Chainsaw by allowing users to reference files hosted on remote locations, such as GitHub raw URLs or other web URLs, directly within their test definitions.
Example URL File Reference¶
apiVersion: chainsaw.kyverno.io/v1alpha1
kind: Test
metadata:
name: test-name
spec:
skip: false
concurrent: false
skipDelete: false
timeouts:
apply: 10s
assert: 10s
error: 10s
steps:
# first step
# apply a Kubernetes manifest hosted at a GitHub raw URL
- try:
- apply:
file: https://raw.githubusercontent.com/username/repo/branch/path/to/configmap.yaml
# second step
# execute assert statements against existing resources
# using a file hosted on another web URL
- try:
- assert:
file: https://example.com/path/to/configmap-assert.yaml
# third step
# execute error statements against existing resources
- try:
- error:
file: https://mywebsite.com/path/to/configmap-error.yaml
