How to convert Selenese (html) to Python programmatically?

Question

How would I convert test cases made by Selenium IDE to Python without exporting every test case by hand? Is there any command line converter for that job?

In the end I want to use Selenium RC and Pythons build in unittest to test my websites.

Thanks a lot.

Update:

I started to write a converter but its too much work to implement all the commands. Is there any better way?

from xml.dom.minidom import parse
class SeleneseParser:
 def __init__(self,selFile):
 self.dom = parse(selFile)
 def getTestName(self):
 return self.dom.getElementsByTagName('title')[0].firstChild.data
 def getBaseUrl(self):
 return self.dom.getElementsByTagName('link')[0].getAttribute('href')
 def getNodes(self):
 cmds = []
 nodes = self.dom.getElementsByTagName('tbody')[0].childNodes
 for node in nodes:
 if node.nodeType == node.TEXT_NODE and "\n" in node.data:
 continue
 if node.nodeType == node.COMMENT_NODE:
 cmds.append(node.data)
 if node.nodeType == node.ELEMENT_NODE:
 cmd = []
 for c in node.childNodes:
 if c.nodeType == node.ELEMENT_NODE:
 if len(c.childNodes) == 1:
 cmd.append(c.childNodes[0].data)
 else:
 cmd.append("")
 cmds.append(cmd)
 return cmds

Answer 1

I've started building a Selenese-to-Python parser, PySelenese, which I've posted on Github. Feel free to fork/clone the repository and give it a try: http://github.com/jpstacey/PySelenese .

No there isn't a way but in theory it shouldn't be too difficult to do as all you need to do is have something that uses the python-rc.js to convert the file.

• Vinay Sajip: Yes, but the question asked about a way other than "exporting every test case by hand".
