$.Template.BasePath can't be handled properly

[cyfu]

I added following annotation in helm-unittest/test/data/v3/with-subchart/charts/child-chart/templates/deployment.yaml.

annotations:
  checksum/config: {{ include (print $.Template.BasePath "/configmap.yaml") . | sha256sum }}

And also created the configmap.yaml file in the child-chart/templates folder.

helm template command works well, but helm unittest . produces error:

Error: template: with-subchart/charts/child-chart/templates/deployment.yaml:12:24: executing "with-subchart/charts/child-chart/templates/deployment.yaml" at <include (print $.Template.BasePath "/configmap.yaml") .>: error calling include: template: no template "with-subchart/charts/child-chart/templates/configmap.yaml" associated with template "gotpl"

Attached is the modified with-subchart and console output.

Same issue.

What we are doing in our case is including a sub-chart template to do some dynamic adjustements. This was working with unit test 0.2.8, but stopped working when upgrading to 0.4.1:

{{- $filePath := ( print $.Template.BasePath "../charts/testkube/charts/testkube-api/templates/minio.yaml" ) }}
{{- $filePath = $filePath | replace "templates/../" ""}}
{{- $manifest := include "filePath" $someContext }}

Hello @cyfu, @instriker,

Please take a look at the deployment test in the basic sample project.

To run the tpl functions the helmchart expects that the linked yaml files are part of the helmcht
To isolated the unit tests, the template filter only loads the required files. So to have a valid deployment test with a validation of the configmap hash, it is important to also include the configmap.yaml as part of the templates filter.

Greetings,

Yes it works, thank you!

I didn't figure the best way to handle the templates to reference files inside a chart.yaml, but found *.yaml to be working as in this config:

templates:
- "*.yaml"
tests:
- it: my test
  template: templates/deployment.yaml
  asserts: 
  # ...
