Test2::Env(3pm)

Ok bestie, welcome to the Test2::Env(3pm) page from the Perl Programmers Reference Guide — the official little list of environment variables that Test2 either reads or sets. 💅✨

✨ NAME ✨

Test2::Env — documentation for environment variables used or set by Test2. That’s the whole name vibe. 💖

🦋 DESCRIPTION 🦋

This is a list of environment variables that are either set by, or read by Test2. No cap, that’s the entire mission. 🫶

💅 AUTHOR_TESTING 💅

This env var is read by Test2. When set, Test2 will run tests that are normally skipped unless a module author is doing extra author-specific testing. So it’s like author-mode extra credit. 🧪✨

🤖 AUTOMATED_TESTING 🤖

This env var is read by Test2. When set, it indicates the tests are run by an automated system and no human interaction is possible. Very “robot hands only” energy. 💀

See Test2::Require::AuthorTesting.

🚀 EXTENDED_TESTING 🚀

This env var is read by Test2. When set, it indicates some extended testing that should normally be skipped will be run. Basically the extra-boss-level tests are coming out to play. 🔥

See Test2::Require::ExtendedTesting.

🎪 HARNESS_ACTIVE 🎪

This env var is read by Test2. It is usually set by prove (Test::Harness) or yath (App::Yath). Harness said “I’m here,” and Test2 said “noted.” 👑

🙈 NONINTERACTIVE_TESTING 🙈

This env var is read by Test2. When set, it indicates the testing will not be interactive. No hands-on keyboard chaos, just automated vibes. 🌸

See Test2::Require::NonInteractiveTesting.

🎀 RELEASE_TESTING 🎀

This env var is read by Test2. When set, it indicates that release testing is being done, which may run more tests than normal. Release mode said “more tests, actually.” 💖

See Test2::Require::ReleaseTesting.

🌈 T2_FORMATTER 🌈

This can be used to set the formatter that Test2 will use. If set to a string without a + prefix, then Test2::Formatter:: will be added to the start of the module name. If + is present it will be stripped and no further modification will be made to the module name. Custom formatter slay, periodt. ✨

🧚 T2_IN_PRELOAD 🧚

Test2 sets this when preload mode is active. This is mainly used by App::Yath and similar tools that preload Test2, then fork to run tests. Preload-and-fork besties, this one’s for you. 🦋

📏 TABLE_TERM_SIZE 📏

This is used to set a terminal width for things like diagnostic message tables. Gotta make those tables fit, fr fr. 🎀

⭐ TEST2_ACTIVE ⭐

Test2 sets this variable when tests are running. It’s giving “tests are literally happening right now.” 💅

🔌 TEST2_ENABLE_PLUGINS 🔌

This can be used to force plugins to be loaded when the Test2 API is loaded. It takes a list of one or more plugin names separated by comma. If the module name does not have a + in front of it then the Test2::Plugin:: namespace is assumed and added. If a + is present at the start of a module name it will be stripped and no further modification will be made.

Examples:

TEST2_ENABLE_PLUGINS=BailOnFail
Test2_ENABLE_PLUGINS=SRand,+My::Plugin::Name

🧪 TEST_ACTIVE 🧪

Set by Test2 when tests are running. Yep, another “tests are active” flag — iconic behavior. 🌟

🔥 TS_MAX_DELTA 🔥

Used to determine how many max lines of output will be provided when is() finds a deep data structure mismatch. Deep mismatch diagnostics, but make it bounded. 😭
