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

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

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 Definitions
