qaf-cucumber-无法在BDD2方案大纲中引用来自CSV数据提供程序的数据

Question

上下文

我想使用qaf-cucumber来利用QAF功能，而仍将Cucumber与JUnit一起使用。主要是，我需要QAF的数据提供程序功能，允许将.csv中的方案示例外部化，以便在多个方案和功能中使用它们。

Junit：4.12

黄瓜：5.0.0-RC2

QAF：2.1.15

qaf-cucumber：2.1.15-beta-3（最新版本，因为尚未发布）

问题

在方案上方使用QAF标签@dataFile来指定.csv的位置时：

• 我得到了INFO跟踪“ c.qmetry.qaf.automation.util.CSVUtil-加载csv数据文件：src / test / resources / data / testdata.csv”，正如预期的那样。

• 该场景执行的次数与预期的.csv中的示例行一样多。

• 在步骤中，将像<column1>或${column1}之类的引用视为字符串，而不是引用.csv中的列值。

也（但我不寻求这些解决方案）：

1. QAF documentation about CSV表示BDD2的@dataFile:resources/data/logintestdata.csv等效于Examples: {"dataFile":"resources/data/logintestdata.csv"}，但是第二个不会触发任何情况，就好像没有给出任何示例。

2. QAF documentation about BDD2 syntax表示使用QAF标签Scenario时应使用小黄瓜关键字@dataFile。尽管如此，这样做仍会在下面给出堆栈跟踪。而是必须使用关键字Scenario Outline。

我很清楚将这两个错误归咎于qaf-cucumber，尤其是考虑到它的发展还很早。

@RunWith(Cucumber.class)
@CucumberOptions(
        features = "src/test/resources/features",
        glue = "com.steps",
        plugin = {"com.qmetry.qaf.automation.cucumber.QAFCucumberPlugin", "pretty"})

src/test/resources/features的特征

Feature: Cucumber scenario with QAF data provider

  @dataFile:src/test/resources/data/testdata.csv
  Scenario Outline: Test

src/test/resources/data处的testdata.csv

#col.seperator=|
column1|column2
example1_column1|example1_column2
example2_column1|example2_column2
进入src/test/java/com/steps的步骤

public class TestSteps {

    @Given("my scenario works with the examples {string} and {string}")
    public void myScenarioWorks(String value1, String value2) {
         // value1 equals "<column1>" and value2 equals "<column2>" !
    }
}

上下文我想使用qaf-cucumber来利用QAF功能，同时仍将Cucumber与JUnit一起使用。主要是，我需要QAF来提供其数据提供程序功能，从而可以将场景示例外部化...

Answer 1

我尝试使用2.1.15，它对我有用。我在使用qaf-黄瓜2.1.15-beta-3时也获得了上述行为，但是当更新到qaf-黄瓜2.1.15时，它的工作正常。
