Method Detail

• fact

  public static Fact fact(String key,
                          @NullableDecl
                          Object value)

  Creates a fact with the given key and value, which will be printed in a format like "key: value." The value is converted to a string by calling String.valueOf on it.

• simpleFact

  public static Fact simpleFact(String key)

  Creates a fact with no value, which will be printed in the format "key" (with no colon or value).

  In most cases, prefer key-value facts, which give Truth more flexibility in how to format the fact for display. simpleFact is useful primarily for:

  • messages from no-arg assertions. For example, isNotEmpty() would generate the fact "expected not to be empty"
  • prose that is part of a larger message. For example, contains() sometimes displays facts like "expected to contain: ..." "but did not" "though it did contain: ..."

• toString

  public String toString()

  Returns a simple string representation for the fact. While this is used by the old-style messages and TruthFailureSubject output, we're moving away from the old-style messages and onto makeMessage(com.google.common.collect.ImmutableList<java.lang.String>, com.google.common.collect.ImmutableList<com.google.common.truth.Fact>), which aligns facts horizontally and indents multiline values.

  Overrides:

  toString in class Object
