我想知道是否有一种方法可以在步骤方法中访问示例表行数据而不将其作为参数传递?

故事档案:

Given I am logged in
When I create a trade
Then a trade should be created

Examples:
|data1|data2|
|11111|22222|
|33333|44444|

步骤文件:

@When("I create a trade")
public void createTrade(@Named("data1") String data1, @Named("data2") String data2){
    //code to create trade using data1 and data2
}

以上工作正常,但我想要一种从方法中的示例表访问数据行的方法。(我想这样做的原因是因为所有列可能不会出现在每个故事的示例表中,而且我发现如果我在 step 方法中说 3 * @Named 作为参数,但其中之一是从实际示例表中丢失然后它无法运行。)

@When("I create a trade")
public void createTrade(){
    //check if there is a data1 column, if so get value and do something
    //check if there is a data2 column, if so get value and do something
}

谢谢你的帮助

您可以实现一个新的参数转换器,然后将表作为对象传递。例如,在我们的项目中,我们构建了 ExamplesTableConverter(注意:有一个我们没有测试的盒子 JBehave 转换器):

public class ExamplesTableConverter extends ParameterConverters.ExamplesTableConverter {
private final ExamplesTableFactory factory;
private static final String ROW_SEPARATOR = "\n";
private static final String FIELD_SEPARATOR = "|";

public ExamplesTableConverter(){
    this(new ExamplesTableFactory());
}

public ExamplesTableConverter(ExamplesTableFactory factory){
    this.factory = factory;
}

@Override
public boolean accept(Type type) {
    if (type instanceof Class<?>){
        return ExamplesTable.class.isAssignableFrom((Class<?>) type);
    }
    return false;  //To change body of implemented methods use File | Settings | File Templates.
}

@Override
public Object convertValue(String tableAsString, Type type) {
    System.out.println(tableAsString);
    String[] rows = tableAsString.split(ROW_SEPARATOR);
    StringBuffer resultString = new StringBuffer();
    resultString.append(rows[0]);
    resultString.append(ROW_SEPARATOR);

    for(int i=1; i<rows.length; i++){
        String originRow = rows[i];
        List<String> rowValues = TableUtils.parseRow(originRow, FIELD_SEPARATOR, true);

        String translatedRow = translateRow(rowValues);
        resultString.append(translatedRow);
        resultString.append(ROW_SEPARATOR);
    }
    System.out.println(resultString.toString());
    Object table = factory.createExamplesTable(resultString.toString());
    return table;
    //return null; 
}

private String translateRow(List<String> rowValues) {
    StringBuffer result = new StringBuffer(FIELD_SEPARATOR);

    for(String field : rowValues){
        try{
        result.append(translate(field));
        result.append(FIELD_SEPARATOR);}
        catch (LocalizationException e){
            e.printStackTrace();
            //Need do something here to handle exception
        }
    }
    return result.toString(); 
}

}

那么您需要将该转换器添加到您的配置中:

configuration.parameterConverters().addConverters(new ExamplesTableConverter());

创建一个使用它的方法

@When("create parameters of type $param1 from the next table: $table")    
public void doThis(@Named("param1") String param1, @Named("table") ExamplesTable table)

最后,在故事中使用它:

When create parameters of type type1 from the next table:
|FirstName|LastName|
|Donald|Duck|

这将允许您迭代表。

设想:-

Given data insert in DemoSheet
 |demoNumber|demoName|
 |101|Demo1|
 |102|Demo2|
 |103|Demo3|
 |104|Demo4|
 |105|Demo5|

从场景中获取值的java类:-

@Given("data insert in DemoSheet $parameterTable")
public void setDataToSheet(ExamplesTable parametersTable)
        throws RowsExceededException, WriteException, IOException {

    List<String> demonum = new ArrayList<String>();
    List<String> demoname = new ArrayList<String>();

    for (Map<String, String> row : parametersTable.getRows()) {
        Iterator it = row.entrySet().iterator();
        while (it.hasNext()) {
            Map.Entry pairs = (Map.Entry) it.next();
            if (pairs.getKey().equals("demoNumber")) {
                demonum.add((String) pairs.getValue());
            } else if (pairs.getKey().equals("demoName")) {
                demoname.add((String) pairs.getValue());
            }
        }
    }
    for(String s:demonum)
    {
       System.out.println(s.getDemonum);
       System.out.println(s.getDemoname);
    }
}

我们可以在这里使用示例表参数获取多行,我将多行从场景传递到 java 类..
