This PR adds case insensitive duplicate detection across resources and functions during schema binding. We do not expect this to break existing schemas, since no language backend (except Pulumi YAML) correctly handles this case. Fixes #17796 |

SDK Codegen Tests
TestSDKCodegen runs the complete set of SDK code generation tests against a particular language's code generator. It also verifies that the generated code is structurally sound.
The test files live in pkg/codegen/testing/test/testdata
and
are registered in the following globals in pkg/codegen/testing/test.
- sdk_driver.go:
PulumiPulumiSDKTests
- program_driver.go:
PulumiPulumiProgramTests
- program_driver.go:
PulumiPulumiYAMLProgramTests
An SDK code generation test files consists of a schema and a set of expected outputs for each language. Each test is structured as a directory that contains that information:
testdata/
my-simple-schema/ # i.e. `simple-enum-schema`
schema.(json|yaml)
go/
python/
nodejs/
dotnet/
...
The schema is the only piece that must be manually authored.
Once the schema has been written, the actual codegen outputs can be
generated by running the following in pkg/codegen
directory:
PULUMI_ACCEPT=true go test ./...
This will rebuild subfolders such as go/
from scratch and store
the set of code-generated file names in go/codegen-manifest.json
.
To generate the code for a specific directory in testdata,
run the following instead:
PULUMI_ACCEPT=true go test ./... -run TestGenerate/$dirName
If these outputs look correct, they need to be checked into git and will then serve as the expected values for the normal test runs:
$ go test ./...
That is, the normal test runs will fail if changes to codegen or
schema lead to a diff in the generated file set. If the diff is
intentional, it can be accepted again via PULUMI_ACCEPT=true
.
Writing Program Tests on Generated Code
To support running unit tests over the generated code, the tests
also support mixing in manually written $lang-extras
files into
the generated tree. For example, given the following input:
testdata/
my-simple-schema/
schema.json
go/
go-extras/
tests/
go_test.go
The system will copy go-extras/tests/go_test.go
into
go/tests/go_test.go
before performing compilation and unit test
checks over the project generated in go
.
