Python Library Core

Tools to ease creating larger test libraries forRobotFramework using Python. The Robot Frameworkhybridanddynamic libraryAPIgives more flexibility for library than the static library API, but theyalso sets requirements for libraries which needs to be implemented inthe library side. PythonLibCore eases the problem by providing simplerinterface and handling all the requirements towards the Robot Frameworklibrary APIs.

Code is stable and is already used bySeleniumLibraryandBrowser library.Project supports two latest version of Robot Framework.

Usage

There are two ways to use PythonLibCore, either byHybridCore or by usingDynamicCore.HybridCore provides support forthe hybrid library API andDynamicCore provides support for dynamic library API.Consult the Robot FrameworkUserGuide,for choosing the correct API for library.

Regardless which library API is chosen, both have similar requirements.

1. Library must inherit either theHybridCore orDynamicCore.
2. Library keywords must be decorated with Robot Framework@keyworddecorator.
3. Provide a list of class instances implementing keywords tolibrary_components argument in theHybridCore orDynamicCore__init__.

It is also possible implement keywords in the library main class, by marking method with@keyword as keywords. It is not required pass main library instance in thelibrary_components argument.

All keyword, also keywords implemented in the classes outside of themain library are available in the library instance as methods. Thisautomatically publish library keywords in as methods in the Pythonpublic API.

The example in below demonstrates how the PythonLibCore can be used witha library.

Example

"""Main library."""fromrobotlibcoreimportDynamicCorefrommystuffimportLibrary1,Library2classMyLibrary(DynamicCore):"""General library documentation."""def__init__(self):libraries=[Library1(),Library2()]DynamicCore.__init__(self,libraries)@keyworddefkeyword_in_main(self):pass

"""Library components."""fromrobotlibcoreimportkeywordclassLibrary1(object):@keyworddefexample(self):"""Keyword documentation."""pass@keyworddefanother_example(self,arg1,arg2='default'):passdefnot_keyword(self):passclassLibrary2(object):@keyword('Custom name')defthis_name_is_not_used(self):pass@keyword(tags=['tag','another'])deftags(self):pass

Plugin API

It is possible to create plugin API to a library by using PythonLibCore.This allows extending library with external Python classes. Plugins canbe imported during library import time, example by defining argumet inlibrary [__init__]{.title-ref} which allows defining the plugins. Itis possible to define multiple plugins, by seperating plugins with withcomma. Also it is possible to provide arguments to plugin by seperatingarguments with semicolon.

fromrobot.api.decoimportkeyword# noqa F401fromrobotlibcoreimportDynamicCore,PluginParserfrommystuffimportLibrary1,Library2classPluginLib(DynamicCore):def__init__(self,plugins):plugin_parser=PluginParser()libraries=[Library1(),Library2()]parsed_plugins=plugin_parser.parse_plugins(plugins)libraries.extend(parsed_plugins)DynamicCore.__init__(self,libraries)

When plugin class can look like this:

classMyPlugi:@keyworddefplugin_keyword(self):return123

Then Library can be imported in Robot Framework side like this:

Library${CURDIR}/PluginLib.pyplugins=${CURDIR}/MyPlugin.py

Translation

PLC supports translation of keywords names and documentation, but arguments names, tags and typescan not be currently translated. Translation is provided as a file containingJson and as aPath object. Translation is provided intranslation argument in theHybridCore orDynamicCore__init__. Providing translationfile is optional, also it is not mandatory to provide translation to all keyword.

The keys of json are the methods names, not the keyword names, which implements keyword. Valueof key is json object which contains two keys:name anddoc.name key contains the keywordtranslated name anddoc contains keyword translated documentation. Providingdoc andname is optional, example translation json file can only provide translations onlyto keyword names or only to documentatin. But it is always recomended to provide translation tobothname anddoc.

Library class documentation and instance documetation has special keys,__init__ key willreplace instance documentation and__intro__ will replace libary class documentation.

Example

If there is library like this:

frompathlibimportPathfromrobotlibcoreimportDynamicCore,keywordclassSmallLibrary(DynamicCore):"""Library documentation."""def__init__(self,translation:Path):"""__init__ documentation."""DynamicCore.__init__(self,[],translation.absolute())@keyword(tags=["tag1","tag2"])defnormal_keyword(self,arg:int,other:str)->str:"""I have doc        Multiple lines.        Other line.        """data=f"{arg}{other}"print(data)returndatadefnot_keyword(self,data:str)->str:print(data)returndata@keyword(name="This Is New Name",tags=["tag1","tag2"])defname_changed(self,some:int,other:int)->int:"""This one too"""print(f"{some}{type(some)},{other}{type(other)}")returnsome+other

And when there is translation file like:

{"normal_keyword":{"name":"other_name","doc":"This is new doc"},"name_changed":{"name":"name_changed_again","doc":"This is also replaced.\n\nnew line."},"__init__":{"name":"__init__","doc":"Replaces init docs with this one."},"__intro__":{"name":"__intro__","doc":"New __intro__ documentation is here."},}

Thennormal_keyword is translated toother_name. Also this keyword documentions istranslted toThis is new doc. The keyword isname_changed is translted toname_changed_again keyword and keyword documentation is translted toThis is also replaced.\n\nnew line.. The library class documentation is translatedtoReplaces init docs with this one. and class documentation is translted toNew __intro__ documentation is here.
