This Rust program is used to perform simple integration tests on programs through a JSON configuration file.
Usage: tiny-integration-tester [options]
| Arg | Long name | Description | |-----|-----------------|----------------------------------------------| | -f | --file NAME | set json tests file name | | -t | --timeout VALUE | set the default timeout in ms for all tests | | -h | --help | print this help menu | | -v | --version | print the program version |
After creating a new project with the command cargo new hello, create a file named test.json like this :
[
{
"command" : "./target/debug/hello",
"stdout" : "Hello, world!\n"
},
{
"command" : "./target/debug/hello",
"stdout" : "Hello, dummy!\n"
}
]
Then simply run cargo build then tiny-integration-tester :
Executing command: "./target/debug/hello" with args: []
OK!
Executing command: "./target/debug/hello" with args: []
FAIL!
YOU GOT: Output {
status: ExitStatus(
unix_wait_status(
0,
),
),
stdout: "Hello, world!\n",
stderr: "",
}
BUT DESIRED OUTPUT IS: Output {
status: ExitStatus(
unix_wait_status(
0,
),
),
stdout: "Hello, dummy!\n",
stderr: "",
}
result: 1 / 2
You can set these values into the json test file :
| Field | Definition | Type | Comment | |-----------|-------------------------|---------------------------|-----------------------| | command | command to run | String | Mandatory | | stdout | FD stdout | String | | | stderr | FD stderr | String | | | stdin | FD stdin | String | | | args | command arguments | Array of String | | | envs | command envs args | Array of (String, String) | json tuple is [1, 2] | | env_clear | clear environment | Boolean | clear all env if true | | status | process exit status | Hexadecimal String | 0xHHLL depends of OS | | timeout | kill process after X ms | Unsigned Integer | unit ms |

Be careful with trailing commas at the end in a JSON file.
