Relates to

Improving test infrastructure and type safety in Twitter client tests

Risks

Low - Most changes are isolated to test files. The only production code change is setting TWITTER_MAX_TWEETS_PER_DAY to default to 10 tweets per day if not specified. This maintains existing behavior as seen in tests.

Background

What does this PR do?

  • Keep env property in test runtime mocks for better real-world simulation
  • Add TestAgentRuntime type to handle type safety in test mocks without implementing full IAgentRuntime interface (30+ properties)
  • Remove duplicate TWITTER_MAX_TWEET_LENGTH in favor of MAX_TWEET_LENGTH
  • Add TWITTER_MAX_TWEETS_PER_DAY to schema with default value of 10 tweets per day
  • Standardize mock configuration across test files
  • Fix type casting issues in environment tests

This change improves type safety while maintaining realistic test scenarios and reduces test complexity by only mocking necessary runtime properties.

What kind of change is this?

Bug fixes (non-breaking change which fixes an issue)

Documentation changes needed?

My changes do not require a change to the project documentation.

Testing

Where should a reviewer start?

  1. packages/client-twitter/tests/environment.test.ts
  2. packages/client-twitter/tests/base.test.ts
  3. packages/client-twitter/tests/post.test.ts

Detailed testing steps

  • Run the Twitter client tests:
    cd packages/client-twitter
    pnpm test
  • Verify all Twitter client tests pass
  • Check that mock configurations are consistent across test files
  • Verify the build succeeds:
    cd packages/client-twitter
    pnpm build

packages/client-twitter/__tests__/test-utils.ts (1)

3-7: LGTM! Consider adding JSDoc comments.

The TestAgentRuntime type is well-designed, using Partial<IAgentRuntime> to avoid implementing unnecessary interface methods while adding essential test properties.

Add JSDoc comments to describe the purpose and usage:

+/**
+ * Runtime implementation for testing purposes.
+ * Provides environment configuration access without requiring full IAgentRuntime implementation.
+ */
export type TestAgentRuntime = Partial<IAgentRuntime> & {
    env: Record<string, string>;
    getEnv: (key: string) => string | null;
    getSetting: (key: string) => string | null;
};
packages/client-twitter/__tests__/environment.test.ts (2)

35-38: Type assertions are handled correctly.

The code properly casts TestAgentRuntime to IAgentRuntime when calling validateTwitterConfig.

Consider creating a helper function to reduce repetitive type casting:

const asIAgentRuntime = (runtime: TestAgentRuntime): IAgentRuntime => runtime as IAgentRuntime;

65-67: Reduce duplicate type casting code.

Multiple instances of the same type casting pattern could be simplified using a helper function.

Use the suggested helper function to simplify these calls:

-const config = await validateTwitterConfig(wildcardRuntime as IAgentRuntime);
+const config = await validateTwitterConfig(asIAgentRuntime(wildcardRuntime));

Also applies to: 83-85, 101-103

packages/client-twitter/src/environment.ts (1)

228-232: Consider adding validation for positive values.

While safeParseInt ensures a minimum of 1, consider adding explicit validation in the schema to document this constraint:

-    TWITTER_MAX_TWEETS_PER_DAY: z.number().int().default(10),
+    TWITTER_MAX_TWEETS_PER_DAY: z.number().int().min(1).default(10),

packages/client-twitter/__tests__/base.test.ts (2)

38-55: Configuration properties are well organized.

The new properties provide comprehensive test coverage for Twitter client configuration.


69-69: Test assertion updated correctly.

The assertion now uses MAX_TWEET_LENGTH instead of TWITTER_MAX_TWEET_LENGTH, maintaining consistency with the configuration changes.

packages/client-twitter/__tests__/post.test.ts (1)

48-65: Configuration matches base.test.ts.

The mockConfig changes maintain consistency across test files, which is crucial for reliable testing.

packages/client-twitter/src/environment.ts (2)

68-68: LGTM! Good addition of rate limiting.

The new field is well-typed and has a sensible default value.


77-78: Formatting looks good.

- Keep env property in test runtime mocks for better real-world simulation
- Add TestAgentRuntime type to handle type safety in test mocks without implementing full IAgentRuntime interface (30+ properties)
- Remove duplicate TWITTER_MAX_TWEET_LENGTH in favor of MAX_TWEET_LENGTH
- Add TWITTER_MAX_TWEETS_PER_DAY to schema with default value

🧹 Nitpick comments (4)
packages/client-twitter/__tests__/post.test.ts (1)

48-49: Use more obvious test credentials.

Even in tests, it's better to use clearly fake credentials like test_password and [email protected] to prevent any confusion with real credentials.

-            TWITTER_PASSWORD: 'hashedpassword',
-            TWITTER_EMAIL: '[email protected]',
+            TWITTER_PASSWORD: 'test_password',
+            TWITTER_EMAIL: '[email protected]',
packages/client-twitter/__tests__/test-utils.ts (1)

7-14: Consider making required properties explicit

Instead of using Partial, consider explicitly listing required properties to prevent accidental omissions in tests.

-export type TestAgentRuntime = Partial<IAgentRuntime> & {
+export type TestAgentRuntime = Pick<IAgentRuntime, 'getEnv' | 'getSetting'> & {
     env: Record<string, string>;
-    getEnv: (key: string) => string | null;
-    getSetting: (key: string) => string | null;
};
packages/client-twitter/src/environment.ts (2)

68-68: Consider adding maximum limit for tweets per day

While minimum is set to 1, consider adding an upper bound to prevent potential API rate limit issues.

-    TWITTER_MAX_TWEETS_PER_DAY: z.number().int().min(1).default(10),
+    TWITTER_MAX_TWEETS_PER_DAY: z.number().int().min(1).max(100).default(10),

228-232: Verify default value consistency

The default value (10) is duplicated in both schema and validation. Consider extracting to a constant.

+const DEFAULT_MAX_TWEETS_PER_DAY = 10;

 export const twitterEnvSchema = z.object({
-    TWITTER_MAX_TWEETS_PER_DAY: z.number().int().min(1).default(10),
+    TWITTER_MAX_TWEETS_PER_DAY: z.number().int().min(1).default(DEFAULT_MAX_TWEETS_PER_DAY),
 });

 // In validateTwitterConfig:
     TWITTER_MAX_TWEETS_PER_DAY: safeParseInt(
         runtime.getSetting("TWITTER_MAX_TWEETS_PER_DAY") ||
             process.env.TWITTER_MAX_TWEETS_PER_DAY,
-        10
+        DEFAULT_MAX_TWEETS_PER_DAY
     ),

4-4: LGTM! Import changes align with type safety improvements.


55-65: LGTM! Configuration changes improve type safety and standardization.

The changes align well with the PR objectives:

  • Standardized property names (MAX_TWEET_LENGTH)
  • Added type-safe timeline configuration
  • Consistent configuration between runtime and mock
packages/client-twitter/__tests__/test-utils.ts (1)

16-19: Add runtime type validation

The type cast could mask runtime issues. Consider adding runtime checks.

-export const asIAgentRuntime = (runtime: TestAgentRuntime): IAgentRuntime => runtime as IAgentRuntime;
+export const asIAgentRuntime = (runtime: TestAgentRuntime): IAgentRuntime => {
+    if (!runtime.getEnv || !runtime.getSetting) {
+        throw new Error('Invalid TestAgentRuntime: missing required methods');
+    }
+    return runtime as IAgentRuntime;
+};

- Use more obvious test credentials ([email protected], test_password)
- Keep Partial<IAgentRuntime> for better type compatibility
- Extract DEFAULT_MAX_TWEETS_PER_DAY constant for consistency
- Add JSDoc comments to TestAgentRuntime type
- Add asIAgentRuntime helper to reduce type casting

Addresses code review feedback regarding test clarity and type safety.
