Add a test that all our conformance test programs are bindable (#16770)
When I was trying to add a new conformance test I had a typo in the PCL
that I didn't pick up till trying to actually run against the NodeJS
host and runtime. This test ensures we won't try to ship a test to the
runtimes that isn't even bindable.

README.md

pulumi-language-test runs a gRPC interface that language plugins can use to run a suite of standard tests.

Architecture

pulumi-language-test is used to run a standard suite of tests against any compliant language plugin.

The diagram below shows the main interactions and data flows for how this system works.

There are three main actors involved. Firstly test which is a test function coordinating the language plugin and pulumi-language-test. Secondly ptl which is the pulumi-language-test process. Finally uut which is the language plugin actually being tested. This will generally be a grpc server running in the same process as the test method.


sequenceDiagram
    test->>ptl: Start ptl process
    ptl-->>test: Read stdout for ptl address to connect to

    Note right of test: All future calls to ptl are via grpc

    test->>+ptl: GetLanguageTests()
    ptl-->>-test: Returns list of test names

    test->>+uut: Serve
    uut-->>-test: Returns uut server address

    test->>+ptl: PrepareLanguageTests(uut)
    ptl->>+uut: Pack(core)
    uut-->>-ptl: Returns name of core artifact
    ptl-->>-test: Returns `token`

    loop for each test
        test->>+ptl: RunLanguageTest(token, test)
        loop for each sdk used in test
            ptl->>+uut: GeneratePackage(sdk)
            uut-->>-ptl: Write package code to temporary directory
            ptl->>ptl: Verify sdk snapshot
            ptl->>+uut: Pack(sdk)
            uut-->>-ptl: Returns name of sdk artifact
        end

        ptl->>+uut: GenerateProject(test)
        uut-->>-ptl: Write project code to temporary directory
        ptl->>ptl: Verify project snapshot

        ptl->>+uut: InstallDependencies(project)
        uut-->>-ptl: 

        note right of ptl: Execute test with engine
        activate ptl
        ptl->>+uut: Run(project)
        uut-->>-ptl: Return run result
        ptl->>ptl: Run test asserts against run result and snapshot
        deactivate ptl

        ptl-->>-test: Returns test result from asserts
    end

    test->>ptl: sigkill

Meta tests

This module contains a number of _test.go files. These are tests of the conformance test system itself. The actual conformance tests are all defined in tests.go.
