The Conditions Utility Class

The utility class Conditions provides several factory methods for creating Condition instances. These are specialized subclasses of Java 8's Predicate interface and can be used in the following sub-systems:

  • Waiting: @Wait and Wait.until(..)
  • Post Construct Assertions: @PostConstructMustBe(...)
  • Filtering of PageFragement Streams
// ad-hoc finding of page fragments with filter
browser.findMany(".textfield").filter(Conditions.is(Conditions.visible()));
// waiting until a certain condition is met
Wait.until(textField).has(Conditions.text("foo"));

Syntax

Conditions are designed to be readable. They take a lot of inspiration from Hamecrest's Matcher and AssertJ's fluent API. It is generally recommended to use static imports when working with the Conditions class.

We provide two kinds of out of the box conditions in the info.novatec.testit.webtester.conditions package:

  • Syntax operations like Has, Is, Not and Either in order to make conditions more readable
  • Page fragment conditions like Attribute, Visible, Selected etc.
