Python读取tsv文件并评估

Question

I have tsv file which is prepared like:

*Settings*                          
Force, Tags FakeTag                     
Resource    ../../robot_resources/global.tsv                        

*Test, Cases*                           
Testcase1   [Documentation] PURPOSE:                    
    ... Test, checking,,                
    ...                     
    ...                     
    ... PRECONDITION:                   
    ... set,                    
    ... make, sure, that,                   
    ...                     
    ...                                     
    [Setup] stopProcessAndWaitForIt                 
    startAdvErrorTrace                      
    startAdvDumpEvents                      
    stopProcessAndWaitForIt                             
    stopAndDownloadAdvDumpEvents                                

Testcase2   [Documentation] PURPOSE:                    
    ... Test, checking,, if,                
    ...                     
    ...                     
    ... PRECONDITION:   

What i want to do is: - start reading file from Test, Cases - read separatly every testcase: testcase1, testcase2..n (every testcase starts without tab, testcase body starts with tab) - evaluate if all testcases has expresions "startAdvErrorTrace" "startAdvDumpEvents" etc I have in tsv about 50 testcases and want evaluate all file

I'm totally green in developing. I have found some ideas like read csv file as tsv. But i don't know how to achieve my expectations

Answer 1

I don't know what file format this is, but you can do something like this:

items = ("startAdvErrorTrace", "startAdvDumpEvents") # add more as desired
import re
with open("testfile") as infile:
    # skip contents until Test Cases
    contents = re.search(r"(?s)\*Test, Cases\*.*", infile.read())
    cases = contents.split("\n\n") # Split on two consecutive newlines
    for case in cases:
        if not all(item in case for item in items)
            print("Not all items found in case:")
            print(case)

Answer 2

Here's a little script to parse the flags per Testcase. The output is:

Flags per testcase:
{1: ['startAdvErrorTrace', 'startAdvDumpEvents'], 2: []}

And the script is:

usage = {}
flags = ('startAdvErrorTrace', 'startAdvDumpEvents')
with(open(testfile)) as f:
    lines = [line.strip() for line in f.readlines()]

    start_parsing = False
    for line in lines:
        if 'Test, Cases' in line:
            start_parsing = True
            continue

        if parse_cases:
            if 'Testcase' in line:
                case_nr = int(re.findall('\d+', line)[0])
                usage[case_nr] = []
                continue

            for flag in flags:
                if flag in line:
                    usage[case_nr].append(flag)

print 'Flags per testcase:'
usage

Hope that helps.
