Crate ra_ap_test_utils

Assorted testing utilities.

Most notable things are:

• Rich text comparison, which outputs a diff.
• Extracting markup (mainly, $0 markers) out of fixture strings.
• marks (see the eponymous module).

Modules

• bench_fixture
  Generates large snippets of Rust code for usage in the benchmarks.

Macros

• assert_eq_text
  Asserts that two strings are equal, otherwise displays a rich diff between them.

Structs

• AssertLinear
• Fixture
• FixtureWithProjectMeta
• MiniCore

Enums

• RangeOrOffset

Constants

• CURSOR_MARKER
• ESCAPED_CURSOR_MARKER

Functions

• __diff
• add_cursor
  Inserts $0 marker into the text at offset.
• bench
  Utility for writing benchmark tests.
• ensure_file_contents
  Checks that the file has the specified contents. If that is not the case, updates the file and then fails the test.
• extract_annotations
  Extracts //^^^ some text annotations.
• extract_offset
  Infallible version of try_extract_offset().
• extract_range
  Infallible version of try_extract_range().
• extract_range_or_offset
  Extracts TextRange or TextSize depending on the amount of $0 markers found in text.
• extract_tags
  Extracts ranges, marked with <tag> </tag> pairs from the text
• format_diff
• project_root
  Returns the path to the root directory of rust-analyzer project.
• skip_slow_tests
  Returns false if slow tests should not run, otherwise returns true and also creates a file at ./target/.slow_tests_cookie which serves as a flag that slow tests did run.
• try_ensure_file_contents
  Checks that the file has the specified contents. If that is not the case, updates the file and return an Error.

Type Aliases

• FxHashMap
  Type alias for a hashmap using the fx hash algorithm.
