New name for `ApiTestEngine`.

## Design Philosophy

Take full reuse of Python's existing powerful libraries: [`Requests`][requests], [`unittest`][unittest] and [`Locust`][Locust]. And achieve the goal of API automation test, production environment monitoring, and API performance test, with a concise and elegant manner.

## Key Features

- Inherit all powerful features of [`Requests`][requests], just have fun to handle HTTP in human way.
- Define testcases in YAML or JSON format in concise and elegant manner.
- Supports `function`/`variable`/`extract`/`validate` mechanisms to create full test scenarios.
- With `debugtalk.py` plugin, module functions can be auto-discovered in recursive upward directories.
- Testcases can be run in diverse ways, with single testset, multiple testsets, or entire project folder.
- Test report is concise and clear, with detailed log records. See [`PyUnitReport`][PyUnitReport].
- With reuse of [`Locust`][Locust], you can run performance test without extra work.
- CLI command supported, perfect combination with [Jenkins][Jenkins].

## Installation/Upgrade

```bash
$ pip install HttpRunner
```

To upgrade all specified packages to the newest available version, you should add the `-U` option.

If there is a problem with the installation or upgrade, you can check the [`FAQ`](docs/FAQ.md).

To ensure the installation or upgrade is successful, you can execute command `httprunner -V` to see if you can get the correct version number.

```text
$ httprunner -V
HttpRunner version: 0.8.0
```

Execute the command `httprunner -h` to view command help.

```text
$ httprunner -h
usage: httprunner [-h] [-V] [--log-level LOG_LEVEL] [--report-name REPORT_NAME]
[--failfast] [--startproject STARTPROJECT]
[testset_paths [testset_paths ...]]

HttpRunner.

positional arguments:
testset_paths testset file path

optional arguments:
-h, --help show this help message and exit
-V, --version show version
--log-level LOG_LEVEL
Specify logging level, default is INFO.
--report-name REPORT_NAME
Specify report name, default is generated time.
--failfast Stop the test run on the first error or failure.
--startproject STARTPROJECT
Specify new project name.
```

## Write testcases

It is recommended to write testcases in `YAML` format.

And here is testset example of typical scenario: get `token` at the beginning, and each subsequent requests should take the `token` in the headers.

```yaml
- config:
name: "create user testsets."
variables:
- user_agent: 'iOS/10.3'
- device_sn: ${gen_random_string(15)}
- os_platform: 'ios'
- app_version: '2.8.6'
request:
base_url: http://127.0.0.1:5000
headers:
Content-Type: application/json
device_sn: $device_sn

- test:
name: get token
request:
url: /api/get-token
method: POST
headers:
user_agent: $user_agent
device_sn: $device_sn
os_platform: $os_platform
app_version: $app_version
json:
sign: ${get_sign($user_agent, $device_sn, $os_platform, $app_version)}
extract:
- token: content.token
validate:
- {"check": "status_code", "comparator": "eq", "expected": 200}
- {"check": "content.token", "comparator": "len_eq", "expected": 16}

- test:
name: create user which does not exist
request:
url: /api/users/1000
method: POST
headers:
token: $token
json:
name: "user1"
password: "123456"
validate:
- {"check": "status_code", "comparator": "eq", "expected": 201}
- {"check": "content.success", "comparator": "eq", "expected": true}
```

Function invoke is supported in `YAML/JSON` format testcases, such as `gen_random_string` and `get_sign` above. This mechanism relies on the `debugtak.py` hot plugin, with which we can define functions in `debugtak.py` file, and then functions can be auto discovered and invoked in runtime.

For detailed regulations of writing testcases, you can read the [`QuickStart`][quickstart] documents.

## Run testcases

`HttpRunner` can run testcases in diverse ways.

You can run single testset by specifying testset file path.

```text
$ httprunner filepath/testcase.yml
```

You can also run several testsets by specifying multiple testset file paths.

```text
$ httprunner filepath1/testcase1.yml filepath2/testcase2.yml
```

If you want to run testsets of a whole project, you can achieve this goal by specifying the project folder path.

```text
$ httprunner testcases_folder_path
```

When you do continuous integration test or production environment monitoring with `Jenkins`, you may need to send test result notification. For instance, you can send email with mailgun service as below.

```text
$ httprunner filepath/testcase.yml --report-name ${BUILD_NUMBER} \
--mailgun-smtp-username "[e-mail]" \
--mailgun-smtp-password "12345678" \
--email-sender [e-mail] \
--email-recepients ${MAIL_RECEPIENTS} \
--jenkins-job-name ${JOB_NAME} \
--jenkins-job-url ${JOB_URL} \
--jenkins-build-number ${BUILD_NUMBER}
```

## Performance test

With reuse of [`Locust`][Locust], you can run performance test without extra work.

```bash
$ locusts -V
[2017-08-26 23:45:42,246] bogon/INFO/stdout: Locust 0.8a2
[2017-08-26 23:45:42,246] bogon/INFO/stdout:
```

For full usage, you can run `locusts -h` to see help, and you will find that it is the same with `locust -h`.

The only difference is the `-f` argument. If you specify `-f` with a Python locustfile, it will be the same as `locust`, while if you specify `-f` with a `YAML/JSON` testcase file, it will convert to Python locustfile first and then pass to `locust`.

```bash
$ locusts -f examples/first-testcase.yml
[2017-08-18 17:20:43,915] Leos-MacBook-Air.local/INFO/locust.main: Starting web monitor at *:8089
[2017-08-18 17:20:43,918] Leos-MacBook-Air.local/INFO/locust.main: Starting Locust 0.8a2
```

In this case, you can reuse all features of [`Locust`][Locust].

That’s not all about it. With the argument `--full-speed`, you can even start locust with master and several slaves (default to cpu cores number) at one time, which means you can leverage all cpus of your machine.

```bash
$ locusts -f examples/first-testcase.yml --full-speed
[2017-08-26 23:51:47,071] bogon/INFO/locust.main: Starting web monitor at *:8089
[2017-08-26 23:51:47,075] bogon/INFO/locust.main: Starting Locust 0.8a2
[2017-08-26 23:51:47,078] bogon/INFO/locust.main: Starting Locust 0.8a2
[2017-08-26 23:51:47,080] bogon/INFO/locust.main: Starting Locust 0.8a2
[2017-08-26 23:51:47,083] bogon/INFO/locust.main: Starting Locust 0.8a2
[2017-08-26 23:51:47,084] bogon/INFO/locust.runners: Client 'bogon_656e0af8e968a8533d379dd252422ad3' reported as ready. Currently 1 clients ready to swarm.
