v15.0.0

15.0 - 2021-03-30

This is a major refactor of much of tap's internals, and a lot of new features.

BREAKING CHANGES

• Drop the use of the @std/esm module, in favor of native ES Modules.
• Drop the inclusion of typescript by default. (Typescript still supported, but requires that you install it yourself.)
• .jsx files only run automatically when --jsx config is explicitly enabled.
• --check-coverage on by default.
• Drop support for node <10.
• Separate t.has from t.match, so these are distinct.
• Deprecate aliases.
• Do not report on test points filtered with only or grep options.
• Resolve t.test() promise to the child test results, rather than the parent test.
• Remove callback argument from t.beforeEach and t.afterEach. Return a promise if you wish these methods to be async.

NEW FEATURES and BUG FIXES

• Restructure snapshot output folder, and change file extensions to .cjs.
• Add t.compareOptions object to pass options to all the methods that use tcompare (ie, t.has, t.match, t.same, etc.)
• Improved diffing and comparison output for long strings and buffers.
• Add t.before method.
• Add t.mock() API for mocking calls to require() in modules being tested.
• Inherit the t.saveFixture boolean option.
• Create fixtures symbolic links as junctions if pointing at directories.
• Set both FORCE_COLOR and NO_COLOR environment variables appropriately.
• Pull initial TS_NODE_COMPILER_OPTIONS from test environment.
• Run fixture cleanup aysnchronously on t.teardown() to minimize Windows folder locking issues.
• Load .taprc.yml and .taprc.yaml config files if present, and no .taprc is present.

DEPENDENCIES and REFACTORING

• Extract most of the internal functionality to libtap.
• Update nyc to version 15.
• Conditional exports to limit diving into tap's internals except via supported APIs.
