- 11-172: The
Testclass declaration and its method signatures are well-defined, providing clear type annotations for parameters and return types. This significantly improves the usability and type safety of theTestclass in TypeScript projects. However, there are a couple of minor issues to address:
- Line 9: There's an extra semicolon at the end of the import statement. While this is not a syntax error, it's unnecessary and should be removed for consistency and cleanliness.
- General: Ensure that all callback types (
Test.Callback) and option types (Options) are defined and correctly imported or declared within this file or its dependencies. This is crucial for maintaining the integrity and usability of the type declarations.- } from './results';; + } from './results';Please verify that all referenced types (
Test.Callback,Options, etc.) are correctly defined and accessible within this context.
- 174-220: The
Testnamespace provides additional type definitions that are essential for the detailed and specific typing of callback functions, call results, and other utility types used within theTestclass. This is a good practice as it encapsulates related types within the namespace of the class they support, enhancing modularity and readability.- 222-222: Exporting the
Testclass usingexport = Test;is appropriate for this module pattern and ensures compatibility with CommonJS imports. This is a good practice for TypeScript declaration files that correspond to JavaScript modules intended to be used in Node.js environments.lib/test.js (8)
- 15-15: The modification of the

This change is particularly important for environments that may not supportObject.isnatively.- 38-44: The
isErrorConstructorfunction and its type definition (IsErrorConstructor) are well-implemented, providing a robust way to check if a given constructor is one of the standard JavaScript error constructors. This is crucial for error handling and validation within theTestclass methods. However, there's a minor improvement that can be made for readability:
- Consider adding a brief comment explaining the purpose of the
isErrorConstructorfunction and why there are two different implementations based on the environment. This will help future maintainers understand the rationale behind this design choice.Consider adding explanatory comments for the
isErrorConstructorfunction.
- 54-54: The
getTestArgsfunction is correctly annotated with a JSDoc comment, providing type information for its parameters and return type. This enhances code readability and helps TypeScript users understand the expected types, even though this is a JavaScript file.

The
runmethod implementation correctly handles asynchronous test callbacks by supporting both synchronous and Promise-based asynchronous tests. This is a crucial feature for a testing framework, allowing users to write tests that perform asynchronous operations. However, there's a minor improvement that can be made for error handling:
- When handling Promise rejection, consider checking if
erris an instance of a specific error class (e.g.,AssertionError) to provide more detailed error messages or handling specific to assertion errors. This can improve the debugging experience for users.Consider enhancing error handling in the Promise rejection case by checking for specific error types.
- 166-170: The
testmethod correctly creates and manages child test instances, allowing for nested tests. This is a key feature for a testing framework, enabling complex test structures and hierarchies. The implementation is clear and follows best practices for event-driven programming with Node.js'EventEmitter. However, ensure that theTestclass and its methods are thoroughly tested, especially with nested tests, to prevent any potential issues with event handling or state management.Consider adding more comprehensive tests for the
testmethod, particularly focusing on nested tests and event handling.
- 191-194: The
commentmethod implementation is straightforward and correctly emits test result comments as events. This allows for flexible reporting and integration with test runners or other tools. It's a good practice to support comments in testing frameworks, as they can provide valuable context or explanations alongside test results.- 218-218: The
endmethod's implementation correctly handles error reporting and ensures that.end()is called only once per test instance. This is crucial for maintaining the integrity of test results and preventing duplicate or misleading output. However, consider adding more explicit error handling or logging for cases where.end()is called multiple times, to aid in debugging such issues.Consider enhancing error handling for multiple calls to
.end()to improve debuggability.
- 231-231: The
teardownmethod provides a mechanism for registering teardown functions to be executed after a test completes. This is an essential feature for cleaning up resources or state between tests. The implementation is clear and follows best practices. However, ensure that teardown functions are always called, even if a test fails or times out, to prevent resource leaks or interference between tests.Verify that teardown functions are correctly executed in all scenarios, including test failures and timeouts.

The casting of buf to string | ArrayLike<number> is sensible given the function's need to support both string and buffer inputs. However, ensure that this casting is safe by validating the input type before casting, as incorrect assumptions about the type can lead to runtime errors.
Consider adding explicit type checks before casting to ensure safety.

- 11-12: The use of
/** @type {{ browser?: boolean }} */for type casting in the condition to check ifprocessis not running in a browser environment is a clever way to provide type information for TypeScript without changing the runtime behavior. However, ensure that this casting accurately reflects the expected properties of theprocessobject in all execution environments where this code might run.- 16-26: The addition of JSDoc type definitions (
@typedef) enhances the readability and maintainability of the code by providing clear type information for various entities used throughout the file. This is a good practice, especially in a dynamically typed language like JavaScript, as it aids in understanding the expected types of variables and function parameters/returns.- 1-36: > 📝 NOTE

The
getHarnessfunction correctly checks if a harness has already been created and, if not, creates one usingcreateExitHarness. This lazy initialization pattern is efficient. However, consider adding error handling or logging within this function to catch and report potential issues during the harness creation process, especially sincecreateExitHarnessinvolves complex logic.
- 63-63: The
createStreammethod inlazyLoadis well-annotated with types, which improves code clarity. However, ensure that the fallback logic for whenharnessis not yet initialized (creating a new stream and getting the harness with specific options) is thoroughly tested, especially in concurrent scenarios where multiple streams might be created before the harness is initialized.- 87-87: The
createHarnessfunction is well-structured and makes good use of theResultsclass to manage test results. The handling of thetodoIsOKenvironment variable and the autoclose behavior based on configuration are clear examples of thoughtful design. However, consider documenting the rationale behind the decision to automatically close results in most cases but allow for disabling this behavior through configuration.- 211-214: The workaround for TypeScript's bug with circular exports is cleverly documented with a comment. This kind of documentation is crucial for maintainability and understanding the rationale behind certain code patterns that might otherwise seem unusual. Good job on ensuring this hack is well-explained.
lib/results.js (7)
- 28-28: The
coalesceWhiteSpacesfunction is a simple utility that replaces multiple whitespace characters with a single space. This is useful for normalizing strings before output. Consider adding a brief comment explaining the purpose of this function, as utility functions can sometimes be unclear to new contributors or when revisiting the code after some time.- 33-33: The
getNextTestfunction provides a mechanism to retrieve the next test to run, considering the_onlyproperty for focused testing. This logic is crucial for test runners that support.onlysyntax. Ensure that the handling of the_onlyproperty is thoroughly tested, especially in scenarios with nested tests or multiple.onlycalls across different test suites.- 49-49: The
invalidYamlfunction checks if a string contains characters that could be interpreted as YAML indicators. This is an important check for generating accurate TAP output. However, the nameinvalidYamlmight be slightly misleading as it checks for the presence of YAML indicators rather than validating YAML syntax. Consider renaming it to more accurately reflect its purpose, such ascontainsYamlIndicators.- 54-54: The
encodeResultfunction has been modified to handleactualStackdifferently. This change is crucial for providing more detailed error information in test results. Ensure that this modification is compatible with all expected input types forres.actualandres.error, and consider adding tests specifically for this logic to verify its behavior across different error scenarios.- 106-106: The
Resultsconstructor now accepts anoptionsparameter, which is used to configure thetodoIsOKproperty. This enhancement allows for more flexible configuration of test result handling. Ensure that the handling of theoptionsparameter is thoroughly tested, especially with regards to default values and edge cases whereoptionsmight be malformed or contain unexpected properties.- 126-126: The
createStreammethod inResults.prototypehas been enhanced to support both object mode and TAP output. This dual-mode functionality is a significant improvement for test result reporting. However, ensure that the transition between these modes is seamless and well-documented, especially for consumers of theResultsclass who may need to understand how to configure and interpret the output correctly.- 190-190: The
pushmethod inResults.prototypeis straightforward in adding a test to the internal tests array and emitting an_pushevent. This method is crucial for managing the queue of tests to run. Ensure that the interaction betweenpushand other parts of theResultsclass, such asgetNextTest, is well-understood and tested, particularly in scenarios with dynamic test addition or removal.lib/test.d.ts (5)
- 1-1: The inclusion of
EventEmitterandmockPropertytypes at the beginning of the file sets a clear foundation for theTestclass and related functionalities. This is a good practice as it ensures that all necessary types are available and correctly referenced throughout the file.- 13-13: The
Testclass declaration is comprehensive, covering various constructor signatures and properties. This thorough approach ensures that TypeScript can accurately type-check usage of theTestclass in different contexts. However, ensure that all properties and methods of theTestclass are covered, especially those that might be dynamically added or are part of the class's public API but not explicitly declared here.- 41-41: The method
captureFnand other utility methods likecapture,end, etc., are well-typed, providing clear signatures for their usage. This level of detail is crucial for developers to understand how to interact with theTestclass and its utilities. Ensure that the documentation or external resources are available to explain the purpose and usage of these utility methods, as their names alone may not be self-explanatory.- 58-58: The assertion methods (
ok,notOK,error, etc.) are correctly typed, reflecting their usage in theTestclass. This ensures that developers can rely on TypeScript for type checking when writing tests. Consider adding brief comments to these methods to explain their expected usage and any nuances in their behavior, especially for less commonly used assertions.- 185-185: The
Testnamespace declaration provides additional types and interfaces that are essential for advanced usage of theTestclass, such asSyncCallback,Callback, and various types related to method wrapping and interception. This is a good practice as it organizes related types and makes them easily accessible. Ensure that these types are used consistently throughout the project's TypeScript codebase to maintain type safety and clarity.lib/test.js (15)
- 38-44: The JSDoc type annotations added for various typedefs are a good practice for improving code clarity and maintainability. However, ensure that these typedefs accurately reflect the types used throughout the codebase and that they are consistent with the project's existing documentation and type definitions.

The constructor for the
Testclass is well-documented with JSDoc comments, enhancing readability and maintainability. However, the dynamic binding of methods within the constructor usingcallBindis noted. Given the project's constraints (ES3 syntax and no TypeScript), this approach is suitable. To further improve clarity, consider adding a comment explaining why this dynamic binding approach is used, adhering to the guideline that comments should describe "why" or the history/motivation behind code decisions.

Unless you're documenting each overload separately, it's equivalent to inline them all by declaring later parameters optional:
| constructor(name: string, opts: TestOptions, cb: TestCase); | |
| constructor(name: string, opts: TestOptions); | |
| constructor(name: string, cb: Test.Callback); | |
| constructor(name: string); | |
| constructor(name: string, opts?: TestOptions, cb?: TestCase); |
Fun fact: plugin:@typescript-eslint/unified-signatures would catch this. Since you're already using ESLint I'd definitely recommend adding in typescript-eslint for at least this .d.ts file.

You might consider also porting in the types tests from https://github.com/DefinitelyTyped/DefinitelyTyped/blob/e1386bb7838c35504edfdb12876bf0d156d84a2a/types/tap/tap-tests.ts. Since the .d.ts is being hand-written rather than auto-generated from source files, it wouldn't be unheard of for it to fall out of sync.

if it were out of sync, wouldn't tsc fail?

Not in all cases. If you, say, added an extra optional parameter somewhere but never used it, tsc wouldn't think to fail on it.

error: unknown | Error is equivalent to error: unknown. unknown is a top type indicating it could be anything in the world, including Error. plugin:@typescript-eslint/no-redundant-type-constituents
The code later on just checks if (caught.error && typeof caught.error === 'object'), not instanceof Error or an equivalent. So if a caught.error is a non-Error object, the assumption it could be an Error would be wrong.
Can caught.error be something other than Error? If so, what?

technically line 897 doesn't ensure it's an Error, but if that branch is entered, then it's so Error-like as to not make a difference. there doesn't seem to be any way i can do a type assertion without runtime code :-/

Unfortunately, TypeScript doesn't have a way of being informed that every's callbacks should keep narrowing. A type assertion would be the appropriate thing to do here instead of // @ts-expect-error to avoid changing runtime code.
A small runtime change could be to store error and expected as variables after narrowing them.
Alternately, the next version of TypeScript might be nicer about preserving narrowings - I haven't tried.
