Navigation

The navigation offers the ability to chain assertions at different levels and instructions to go inside the sub-elements and return to root element.

There are examples of the navigation in NavigationExamples.java

With a Table or a Request as root

The assertThat(…) static method of org.assertj.db.api.Assertions allows to create a root assertion on a Table.

import static org.assertj.db.api.Assertions.assertThat;

assertThat(table)...

or on a Request.

import static org.assertj.db.api.Assertions.assertThat;

assertThat(request)...

From these root assertions, it is possible to navigate to the sub elements and return to the root element as in the picture below.

                                             origin
                 instantiate+-----------+<-----------=+----------------------+
                 +--------->|On a Column| instantiate |On a Value Of a Column|
                 |          +-----+-----+=----------->+----------------------+
                 :          origin:
+----------------+------+<--------+
|On a Table Or a Request|
+----------------+------+<--------+
                 :          origin:       origin
                 |          +-----+--+<-----------=+-------------------+
                 +--------->|On a Row| instantiate |On a Value Of a Row|
                 instantiate+--------+=----------->+-------------------+

More details on this concept in assertj-db-features-highlight.html#tableorrequestasroot[feature highlight].

With Changes as root

The assertThat(…) static method of org.assertj.db.api.Assertions allows to create a root assertion on Changes.

import static org.assertj.db.api.Assertions.assertThat;

assertThat(changes)...

From this root assertion, it is possible to navigate to the sub elements and return to the root element as in the picture below.

                                                            origin
                                instantiate+-----------+<-----------=+----------------------+
                                +--------->|On a Column| instantiate |On a Value Of a Column|
                                |          +-----+-----+=----------->+----------------------+
                 origin         :          origin:
+-----------+<=-----------+-----+-----+<---------+
|On Changes | instantiate |On a Change|
+-----------+=----------->+-----+-----+<---------+
                                :          origin:       origin
                                |          +-----+--+<-----------=+-------------------+
                                +--------->|On a Row| instantiate |On a Value Of a Row|
                                instantiate+--------+=----------->+-------------------+
