Pass HashMap to DataProvider

[shreeji...@gmail.com]

Hello All,

I am basically looking if a Hash Map can be provided to a @Test annotated method in TestNG.
I am implementing a greedy provider with all my test data extracted from an excel spreadsheet in a Hash Map.

Each key in the Map is a test method in a business sense.

So ideally i want to do something like

@Test
runTest(HashMap data)
such that the test method gets called repeatedly for each key in the HashMap
and the test console prints out X number of tests executed (where X would be the number of keys in the Map).
Please let me know if there is any such feature available.

Currently, i am looping through all the keys in the Map within the test method to perform my steps
and my console prints 1 test method executed which is ideally not what i would like.

Regards
Shreejit

Shreejit,

I haven't understood your usecase well enough. So you would need to explain a bit more with some examples as to what exactly are you trying to do with your excelsheet and how it relates to a Map. Feel free to add more context.

That said and done, is the below sample something that you are looking for ?

Here I am assuming that the entire data set from a datasource such as xls will be one Map, wherein every row will correspond to a key in the Map, and the values represents the column values for each row.

public class HashmapsAsDataLazy {
    private Collection<String> values;
    private String testName;

    @Test (dataProvider = "insideDp")
    public void testMethod(String eachValue) {
        Reporter.log(testName + " has its value was " + eachValue, true);
    }

    @DataProvider (name = "insideDp")
    public Object[][] getMoreData() {
        Object[][] testData = new Object[values.size()][1];
        int i = 0;
        for (String eachValue : values) {
            testData[i++][0] = eachValue;
        }
        return testData;
    }

    @Factory (dataProvider = "dp")
    public HashmapsAsDataLazy(String testName, Collection<String> values) {
        this.values = values;
        this.testName = testName;
    }

    @DataProvider (name = "dp")
    public static Object[][] getData() {
        Map<String, String> object1 = new HashMap<>();
        object1.put("height", "5.5 ft");
        object1.put("weight", "45 kgs");

        Map<String, String> object2 = new HashMap<>();
        object2.put("age", "2");
        object2.put("weight", "45 kgs");

        Map<String, String> object3 = new HashMap<>();
        object3.put("color", "brown");
        object3.put("orientation", "portrait");

        return new Object[][] {
            {"object1", object1.values()},
            {"object2", object2.values()},
            {"object3", object3.values()}
        };
    }
}

Output :
