Developer and business development can be divided into two broad categories: test driven and cognitive development.
Test driven development means you write your tests, and then run them on a small number of users.
For example, you may write a test that determines if a website should be a personal profile or not, or whether a user should have a default password, or even if they should be allowed to register to vote.
Cognitive development is the process of developing and testing the application with a variety of users in order to learn about them and make improvements.
In this article, we will be looking at the cognitive development aspect of WordPress development, and will be using a small subset of the WordPress API to help with this.
The purpose of this article is to explain how to create and run a simple test using the WordPress Developer API, and how to use this to learn more about a given user.
We will use the WP_Query_QueryInterface function to parse the WordPress database.
To begin, we need to create a new WordPress instance: wp_create_instance() .
This will create a newly created WordPress instance, and we will use it to test the new WordPress database that we just created.
If you are using an existing instance, you can use the create_instance function to create an entirely new one, but if you are new to this API, we recommend creating an empty instance, since the API doesn’t support multiple instances.
We’ll need to access this instance through a REST API call.
The REST API is a RESTful web interface that you can access using your favorite REST client like Apache, PHP, or JSP.
For the sake of this tutorial, we are going to use WordPress’ own REST API, so you will need to make sure that you are not using a different version of WordPress.
Create a new database in the WordPress Administration panel, and in the top menu bar, click on the Add New button.
This will add a new MySQL database to the WordPress system, and allow us to access it.
We want to create two new database objects, the WordPress_db object and the WordPressTable_db .
In the top navigation menu, click New Database and then Database Objects.
This opens a dialog box.
Name your new database WordPress_database .
You will need the WordPress name and the Database name.
If your database is already named WordPress_mysql_database , you don’t need to change anything else.
Next, enter the name of your MySQL database, and click Next.
If the name does not appear, you need to press Enter to create the database name.
For more information about MySQL databases, see MySQL.
Select the database, click Next and then Finish.
If everything went well, you should see the following dialog box: You can now connect to the database.
This should take a few seconds.
Once connected, you will see the WordPress table and the database’s name, and if you select the Database as the root for the database you will be able to browse through all of its rows.
When you click on a row, you’ll see a menu with the name and title of the row, and an arrow that indicates which column is currently being displayed.
You can navigate between the rows using the arrow to the left or to the right.
In the example above, the Columns column is displayed first, and the User and Password columns follow.
Now we want to browse to a particular row.
Click on the row that you want to be displayed, and it will show you the results.
If we click on User, we should be able access our WordPress_table_db instance, which we created in the previous step.
We can now start running our tests.
If all went well with your tests so far, you have a database that contains user names, passwords, and so on.
If not, you could start by creating a new instance of your WordPress instance.
We won’t cover creating instances of WordPress in this tutorial.
Now that we have our WordPress instance running, we can access it by visiting our MySQL database instance and navigating to a specific row, or by running the test that we created earlier.
If WordPress is running successfully, it will display the results of our tests, along with an indicator that the test has succeeded.
If a test fails, WordPress will display an error message and will exit.
In our case, if the test passes, we’ll be able browse to our WordPress table by selecting a row and clicking the Browse button.
If it doesn’t work, you might be able use the following SQL query to try and determine the correct database name for our WordPress database: select * from WordPress_users where name = ‘username’ select * where name LIKE ‘database’ select ‘database_name’ where name > ‘wpdb’ Where name = ‘.wpdb'” Now that WordPress is displaying its results, it is time to run some tests.
Let’s create a test to find out whether a particular user has a default WordPress password
