How-to adapt test Data-pool.

 There is such a thing  - Test Data-Pool. Seems to be usefull and there are usage examples but still it is not absolutely clear how-to start.

Given there are tests based on Java+testNG+maven + something else. Let's start:

1. Add maven dependency

 com.griddynamics.qa.datapool

 data-pool

 1.0.1

Specify actual version of course.

2. Greate/find entities package. Add a new entity class

package ru.test.automation.entities;

import com.griddynamics.qa.datapool.DataTypeFactory;

import com.griddynamics.qa.datapool.datatype.IDataType;

/**

 * Represents a BitBucketUser entity.

 */

public interface BitBucketUser extends IDataType {

    static BitBucketUser newUser(){

        return DataTypeFactory.create(BitBucketUser.class);

    }

    Integer getId();

    String getLogin();

    String getPassword();

}

Field set could be different.

3. Greate/find  /resources/data directory and add the data-file

!DataTypeKey 'interface ru.test.automation.entities.BitBucketUser':

- !IDataType {id: 1, login: Uzvr_Odin, password: Klu4slovo}

- !IDataType {id: 2, login: uzvr-Dva, password: derParrollen}

- !IDataType {id: 3, login: uzvr-Tri, password: AEtoKto?}

Let's name the file as ls.yml

4. Highly likely there is a BaseTest so add the following to it

import ru.test.automation.entities.BitBucketUser;

import com.griddynamics.qa.datapool.DataPool;

import static com.griddynamics.qa.datapool.FilterCriterion.by;

import static com.griddynamics.qa.datapool.matchers.StandardMatchers.CONTAINS;

...

@BeforeSuite

protected void loadData() {

    ClassLoader classLoader = getClass().getClassLoader();

    DataPool.load(Paths.get(classLoader.getResource("data/ls.yml").getPath()));

    // TODO: Switch to the approach below when Data-pool 1.0.2 is released.// DataPool.load("data/ls.yml");

}

//TODO: Think about moving into a separate data-access class.

protected BitBucketUser getUserByLogin(String partOfLoginName) {

    return DataPool.find(BitBucketUser.class, by("login", CONTAINS, partOfLoginName)).get(0);

}

5. And finally, within a test

BitBucketUser usr = getUserByLogin("Uzvr_Odin");

loginPage().login(usr.getLogin(), usr.getPassword());
