Revert "[sdk-gen/go] Fix compiling plain element type with plain maps" (#15059)
Reverts pulumi/pulumi#14704 

Fixes #15023 because the PR above changed how object types are
referenced when they are plain. It seems that we only support _shallow_
plain types (only container of nested objects can be plain, not the
object itself) which is why we confused the previous diffs to be
correct.

This reverts the PR previous to fix the breaking change at hand but will
reopen #14662 and make sure the fix for it is to generate `ObjectType`
_and_ `ObjectTypeArgs` regardless of whether the location where the
object type is referenced in the schema.

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.
