Advanced tools
This is a developer preview (public beta) module. Releases might lack important features and might have future breaking changes.
This API is still under active development and subject to non-backward compatible changes or removal in any future version. Use of the API is not recommended in production environments. Experimental APIs are not subject to the Semantic Versioning model.
This library contains helpers for writing unit tests and integration tests for CDK libraries
Write your unit tests like this:
const stack = new Stack();
new MyConstruct(stack, 'MyConstruct', {
...
});
expect(stack).to(someExpectation(...));
Here are the expectations you can use:
Check that the synthesized stack template looks like the given template, or is a superset of it. These functions match logical IDs and all properties of a resource.
matchTemplate(template, matchStyle)
exactlyMatchTemplate(template)
beASupersetOfTemplate(template)
Example:
expect(stack).to(beASupersetOfTemplate({
Resources: {
HostedZone674DD2B7: {
Type: "AWS::Route53::HostedZone",
Properties: {
Name: "test.private.",
VPCs: [{
VPCId: { Ref: 'VPC06C5F037' },
VPCRegion: { Ref: 'AWS::Region' }
}]
}
}
}
}));
If you only care that a resource of a particular type exists (regardless of its logical identifier), and that some of its properties are set to specific values:
haveResource(type, subsetOfProperties)
Example:
expect(stack).to(haveResource('AWS::CertificateManager::Certificate', {
DomainName: 'test.example.com'
// Note: some properties omitted here
}));
