# Record & Generate testcase
|
|
|
|
## capture HTTP request and response
|
|
|
|
Before we write testcases, we should know the details of the API. It is a good choice to use a web debugging proxy tool like `Charles Proxy` to capture the HTTP traffic.
|
|
|
|
For example, the image below illustrates post form data to [`postman-echo.com`][postman-echo].
|
|
|
|

|
|
|
|
## export sessions to HAR file
|
|
|
|
Then we can select captured request & response and export sessions to HTTP archive (.har) file.
|
|
|
|

|
|
|
|

|
|
|
|
## generate testcase with har2case
|
|
|
|
When you get HAR file, you can use builtin command `har2case` to convert it to HttpRunner testcase.
|
|
|
|
### help
|
|
|
|
```text
|
|
$ har2case -h
|
|
usage: har2case har2case [-h] [-2y] [-2j] [--filter FILTER]
|
|
[--exclude EXCLUDE]
|
|
[har_source_file]
|
|
|
|
positional arguments:
|
|
har_source_file Specify HAR source file
|
|
|
|
optional arguments:
|
|
-h, --help show this help message and exit
|
|
-2y, --to-yml, --to-yaml
|
|
Convert to YAML format, if not specified, convert to
|
|
pytest format by default.
|
|
-2j, --to-json Convert to JSON format, if not specified, convert to
|
|
pytest format by default.
|
|
--filter FILTER Specify filter keyword, only url include filter string
|
|
will be converted.
|
|
--exclude EXCLUDE Specify exclude keyword, url that includes exclude
|
|
string will be ignored, multiple keywords can be
|
|
joined with '|'
|
|
```
|
|
|
|
### generate testcase (pytest)
|
|
|
|
Since HttpRunner `3.0.7`, `har2case` will convert HAR file to pytest by default, and it is extremely recommended to write and maintain testcases in pytest format instead of former `YAML/JSON` format.

And it can be run with `hrun` command or the native `pytest` command. In fact, `hrun` is only a wrapper of `pytest`, thus the effect is basically the same.

### generate testcase (YAML/JSON)
|
|
|
|
Of course, you can also generate former `YAML/JSON` testcase format. Just add `-2y/--to-yml` or `-2j/--to-json` argument to `har2case`.
|
|
|
|

The `YAML/JSON` testcase has the same info with `pytest` testcase, and you can run `YAML/JSON` testcase with `hrun` command.
