| 1 | //! Fixtures are strings containing rust source code with optional metadata. | 1 | //! A set of high-level utility fixture methods to use in tests. |
| 2 | //! A fixture without metadata is parsed into a single source file. | ||
| 3 | //! Use this to test functionality local to one file. | ||
| 4 | //! | ||
| 5 | //! Simple Example: | ||
| 6 | //! ``` | ||
| 7 | //! r#" | ||
| 8 | //! fn main() { | ||
| 9 | //! println!("Hello World") | ||
| 10 | //! } | ||
| 11 | //! "# | ||
| 12 | //! ``` | ||
| 13 | //! | ||
| 14 | //! Metadata can be added to a fixture after a `//-` comment. | ||
| 15 | //! The basic form is specifying filenames, | ||
| 16 | //! which is also how to define multiple files in a single test fixture | ||
| 17 | //! | ||
| 18 | //! Example using two files in the same crate: | ||
| 19 | //! ``` | ||
| 20 | //! " | ||
| 21 | //! //- /main.rs | ||
| 22 | //! mod foo; | ||
| 23 | //! fn main() { | ||
| 24 | //! foo::bar(); | ||
| 25 | //! } | ||
| 26 | //! | ||
| 27 | //! //- /foo.rs | ||
| 28 | //! pub fn bar() {} | ||
| 29 | //! " | ||
| 30 | //! ``` | ||
| 31 | //! | ||
| 32 | //! Example using two crates with one file each, with one crate depending on the other: | ||
| 33 | //! ``` | ||
| 34 | //! r#" | ||
| 35 | //! //- /main.rs crate:a deps:b | ||
| 36 | //! fn main() { | ||
| 37 | //! b::foo(); | ||
| 38 | //! } | ||
| 39 | //! //- /lib.rs crate:b | ||
| 40 | //! pub fn b() { | ||
| 41 | //! println!("Hello World") | ||
| 42 | //! } | ||
| 43 | //! "# | ||
| 44 | //! ``` | ||
| 45 | //! | ||
| 46 | //! Metadata allows specifying all settings and variables | ||
| 47 | //! that are available in a real rust project: | ||
| 48 | //! - crate names via `crate:cratename` | ||
| 49 | //! - dependencies via `deps:dep1,dep2` | ||
| 50 | //! - configuration settings via `cfg:dbg=false,opt_level=2` | ||
| 51 | //! - environment variables via `env:PATH=/bin,RUST_LOG=debug` | ||
| 52 | //! | ||
| 53 | //! Example using all available metadata: | ||
| 54 | //! ``` | ||
| 55 | //! " | ||
| 56 | //! //- /lib.rs crate:foo deps:bar,baz cfg:foo=a,bar=b env:OUTDIR=path/to,OTHER=foo | ||
| 57 | //! fn insert_source_code_here() {} | ||
| 58 | //! " | ||
