Predefined Data Types in parseΒΆ
behave uses the parse module (inverse of Python string.format) under the hoods to parse parameters in step definitions. This leads to rather simple and readable parse expressions for step parameters.
Therefore, the following parse types are already supported
in step definitions without registration of any user-defined type:
| Type | Characters Matched | Output |
|---|---|---|
| w | Letters and underscore | str |
| W | Non-letter and underscore | str |
| s | Whitespace | str |
| S | Non-whitespace | str |
| d | Digits (effectively integer numbers) | int |
| D | Non-digit | str |
| n | Numbers with thousands separators (, or .) | int |
| % | Percentage (converted to value/100.0) | float |
| f | Fixed-point numbers | float |
| e | Floating-point numbers with exponent e.g. 1.1e-10, NAN (all case insensitive) | float |
| g | General number format (either d, f or e) | float |
| b | Binary numbers | int |
| o | Octal numbers | int |
| x | Hexadecimal numbers (lower and upper case) | int |
| ti | ISO 8601 format date/time e.g. 1972-01-20T10:21:36Z | datetime |
| te | RFC2822 e-mail format date/time e.g. Mon, 20 Jan 1972 10:21:36 +1000 | datetime |
| tg | Global (day/month) format date/time e.g. 20/1/1972 10:21:36 AM +1:00 | datetime |
| ta | US (month/day) format date/time e.g. 1/20/1972 10:21:36 PM +10:30 | datetime |
| tc | ctime() format date/time e.g. Sun Sep 16 01:03:52 1973 | datetime |
| th | HTTP log format date/time e.g. 21/Nov/2011:00:07:11 +0000 | datetime |
| tt | Time e.g. 10:21:36 PM -5:30 | time |
