table manners for selenium capsules

Here is a simple table, http://www.w3schools.com/html/html_tables.asp


Let us see how Selenium Capsules can help to read the content of it.



The Table class only has two methods now, getHeader and getRows, Stream is a new collection type appears in Java 8.

And here is the test to read the table,


You can see, the table supports type, it will return the type in a Stream. For this table, we define a simple domain class called Person,

    class Person {
        private final String firstName;
        private final String lastName;
        private final int points;

        Person(String firstName, String lastName, int points) {

            this.firstName = firstName;
            this.lastName = lastName;
            this.points = points;
        }

        @Override
        public String toString() {
            return firstName + "|" + lastName + "|" + points;
        }
    }

When we construct the Table, we need to pass a Locator to locate the table and a Mapper to map the contents in a row to the domain class,

        Locator<AbstractPage, Element> locator = Locators.<AbstractPage>element(MAIN).and(element(TABLE));

        Locator<Stream<Element>, Person> mapper = (stream) -> {
            Iterator<String> iterator = stream.map(TEXT).iterator();
            return new Person(iterator.next(), iterator.next(), PARSE_INT.locate(iterator.next()));
        };

The mapper will read all the TD tags in the TR tags and call the new Person for each TR tag.

<tr>
  <td>Jill</td>
  <td>Smith</td> 
  <td>50</td>
</tr>

            return new Person("Jill", "Smith", 50);

it prints this when you run it

Firstname|Lastname|Points|
Jill|Smith|50
Eve|Jackson|94
John|Doe|80
Adam|Johnson|67

The following code is called Method Reference in Java 8.

        table.getRows().forEach(
                System.out::println
        );

It has good table manners.
