在循环中运行测试用例而不是复制代码 [英] Running test case In loop instead of copy the code

问题描述

我在机器人中进行了几次测试.所有测试的idea都是一样的:

- 加载一些参数到模块- 跑步- 将预期结果与实际结果进行比较

不同的测试之间唯一不同的是input 和预期结果.

我想用不同的输入重复运行测试 - 每次迭代都将被视为不同的测试用例 - 而不是 复制相同的代码测试用例并更改输入.

每次迭代都会有自己的测试用例标签\文档\名称(可以说是迭代次数)

例如:

FOR ${TC} IN @{TCS} #TCS 是输入和预期输出的数组*** 测试用例 ***# 编辑标签\文档\测试名称module.load ${TC['input']}${output} = module.runisValid ${output} ${TC['expectedOutput']}结尾

机器人有可能吗?

谢谢:)

解决方案

您可以使用

I have several tests in robot. the Idea of all the tests is identical:

- load some parameter to module
- run
- compare expected to actual results

The only thing is different from test to test, is the input and the expected results.

I would like to run the test repeatedly but with different inputs- and each iteration will be considered as different test case - Instead of copy the same code for all of the test cases and change the inputs.

each iteration will have its own test case tag \ documentation \ name (lets say the iteration number)

for example:

FOR  ${TC}  IN  @{TCS}                            #TCS is array of inputs and expected output
   *** Test Cases ***
   # edit the tag \ documentation \ test name
   module.load  ${TC['input']}
   ${output} =  module.run
   isValid   ${output}  ${TC['expectedOutput']}
END

Is it possible in robot?

Thanks:)

解决方案

You could use the test template feature of the framework, especially the template tests with for loop.

Using it would give the following advantages:

• No code duplication. You need one keyword with the test logic, that will be invoked with all list elements.
• Each iteration will be independent from the other. So if one iteration fails, the next will be still executed.
• It is flexible. The number of iterations is dynamic, you can create an input list in a test or suite setup phase.

Example, note that I am providing my inputs from a variable file.

*** Settings ***
Variables    VariableFile.py

*** Test Cases ***
Math test
    [Template]    Multiplication by 2
    FOR    ${TC}    IN    @{TCS}
        input=${TC.input}    output=${TC.output}
    END
    
*** Keywords ***
Multiplication by 2
    [arguments]    ${input}    ${output}
    ${result}=    Evaluate    ${input}*2
    Should Be Equal As Integers    ${output}    ${result}    Calculated result:${result} is not equal with the expected:${output}

Variable file:

class DataSet(object):

    def __init__(self, input, output):
        self.input = input
        self.output = output
        
    def __str__(self):
        return f'i:{self.input} - o:{self.output}'
        

TCS = [DataSet(1,2), DataSet(2,4), DataSet(3,6), DataSet(3,7), DataSet(4,8)]

This is the output:
