How to read list of maps

Question

I have a TestNG scenario method as

@Then("User Enters Data")
public void feedData(IDataReader dataTable) {
    List<Map<String,String>> data= dataTable.getAllRows();
 }

Data is being returned as a list of map as follows:

[{TextBox=TextValue-1,DropDown=DD-1, Description=Desc-1},
{TextBox=TextValue-2,DropDown=DD-2, Description=Desc-2},
{TextBox=TextValue-3,DropDown=DD-3, Description=Desc-3}]

Selenium script required to feed the above data in the UI. How to read this hence values can be feed to UI in a sequential order. Like

TextBox=TextValue-1,DropDown=DD-1, Description=Desc-1

Then click on save button.

Answer 1

Incase the data is being returned is a List of Map<String,String> as follows:

[{TextBox=TextValue-1, DropDown=DD-1, Description=Desc-1}, {TextBox=TextValue-2, DropDown=DD-2, Description=Desc-2}, {TextBox=TextValue-3, DropDown=DD-3, Description=Desc-3}]

To read the keys and values you can use the following solution:

// System.out.println(list);
// [{TextBox=TextValue-1, DropDown=DD-1, Description=Desc-1}, {TextBox=TextValue-2, DropDown=DD-2, Description=Desc-2}, {TextBox=TextValue-3, DropDown=DD-3, Description=Desc-3}]
for (Map<String, String> map : list) {
    for (Map.Entry<String, String> entry : map.entrySet()) {
        String key = entry.getKey();
        System.out.println(key);
        Object value = entry.getValue();
        System.out.println(value);
    }
}

Output:

TextBox
TextValue-1
DropDown
DD-1
Description
Desc-1
TextBox
TextValue-2
DropDown
DD-2
Description
Desc-2
TextBox
TextValue-3
DropDown
DD-3
Description
Desc-3
