Fix TypeScript compilation errors and runtime TypeError in AISKU async tests by correctly handling asserts() array return #2602

Copilot · 2025-07-07T20:59:06Z

This PR addresses both TypeScript compilation errors and a critical runtime error in AISKU async unit tests by migrating from the deprecated testCaseAsync pattern to the modern _asyncQueue() pattern and correctly handling the asserts() method return value.

Problem

The async test migration had two issues:

TypeScript compilation errors from calling .add() on regular arrays instead of async queue objects:
```
Error: Property 'add' does not exist on type '(() => void)[]'
```

Runtime error causing test failures:

TypeError: nextTestStep is not a function

Root Cause

The asserts() method returns an array of 2 functions [basicAssertFunction, pollingAssertFunction], but the migrated code was incorrectly doing:

// Wrong - tries to add entire array to queue
return this._asyncQueue().add(this.asserts(1));

This caused the runtime error because the async queue expected individual functions, not arrays.

Solution

Fixed the pattern to properly handle the array return:

// Correct - extracts and adds each function individually
let asserts = this.asserts(1);
return this._asyncQueue()
    .add(asserts[0])     // Basic assert function
    .add(asserts[1]);    // Polling assert function

Files Fixed

SnippetInitialization.Tests.ts - Fixed 54 instances of incorrect asserts() usage
applicationinsights.e2e.tests.ts - Fixed 32 instances of incorrect asserts() usage

All async tests now use the proper _asyncQueue() pattern with correct function chaining, resolving both compilation errors and the runtime TypeError.

Fixes #2601

AISKU/Tests/Unit/src/CdnThrottle.tests.ts

-                    let loggingSpy = this.sandbox.stub(_logger, 'throwInternal');
-                    Assert.equal(loggingSpy.called, 0);
+            test: () => {
+                return this._asyncQueue().add(() => {


for the original code before .concat, put them before return this._asyncQueue().add, for example

test: () => { let doc = getGlobal(); hookFetch((resolve) => { // global instance cannot access test private instance AITestClass.orgSetTimeout(function() { resolve( doc["res"]); }, 0); }); this.fetchStub = this.sandbox.spy((doc as any), "fetch"); this.init = new ApplicationInsights({ config: { instrumentationKey: TestInstrumentationKey, featureOptIn : {["iKeyUsage"]: {mode: FeatureOptInMode.disable}}, extensionConfig : {["AppInsightsCfgSyncPlugin"] : { syncMode: ICfgSyncMode.Receive, cfgUrl: "testurl" }} } }); this.init.loadAppInsights(); this._ai = this.init; return this._asyncQueue().add(()=> ...}

The first step of each test should be part of the initial test function, So that all subsequent steps have access to the variables and values from this initial step for any additional context

Fixed in commit ad44d74. Moved synchronous setup code out of the .add() calls and placed it directly in the test: () => {} function before return this._asyncQueue(). This correctly follows the pattern where setup code that was in steps: [() => {...}] before .concat() should be executed synchronously before the async queue operations.

Fixed in commit 3f934f6. Moved all synchronous setup code out of .add() calls to execute directly in the test functions before return this._asyncQueue(). This ensures that variables and values from the initial setup are accessible to subsequent async operations, following the same pattern already correctly implemented in CdnThrottle.tests.ts.

- Move synchronous setup code out of .add() calls and place before return this._asyncQueue() - Applies to CdnThrottle.tests.ts where setup code was followed by .concat() - Addresses feedback from code review comment on proper migration pattern Co-authored-by: Karlie-777 <79606506+Karlie-777@users.noreply.github.com>

- Moved all synchronous setup code from .add() calls to execute directly in test functions - Applied to remaining instances in SnippetInitialization.Tests.ts (5 tests) - Applied to remaining instances in applicationinsights.e2e.tests.ts (6 tests) - Now following the same pattern as CdnThrottle.tests.ts where setup code runs before return this._asyncQueue() - Variables and values from initial setup are now accessible to subsequent async operations Co-authored-by: Karlie-777 <79606506+Karlie-777@users.noreply.github.com>

be consistent and use add or concat, as they are aliases of each other

Fixed in commit 2cd8fdb. Standardized all async queue calls to consistently use .concat() across all migrated test files, since .add() and .concat() are aliases as noted.

Changed to use .add() consistently across all migrated test files in commit f0b6138. All async queue operations now use the .add() method instead of .concat() for consistency.

fix failing tests

Fixed formatting issue in commit 69a7336. Could you provide more details about which specific tests are failing? The async test pattern migrations follow the requested pattern with synchronous setup code moved before the asyncQueue calls. I'd like to address the specific test failures you're seeing.

fix error:

Actual: undefined
...

Fixed in commit 646044a. The "TypeError: nextTestStep is not a function" error was caused by the asserts() method returning an array of 2 functions [function1, pollingAssertFunction], but the migrated code was incorrectly calling .add(this.asserts(...)) which tried to add the entire array instead of the individual functions.

The fix properly handles the array return by extracting and adding each function separately:

let asserts = this.asserts(1);
return this._asyncQueue()
    .add(asserts[0])
    .add(asserts[1]);

Fixed 86 instances total across both test files. All TypeScript compilation errors and the runtime error are now resolved.
