Release Notes

google/truth (com.google.truth:truth)

v1.4.5: 1.4.5

• Changed assertions like assertThat(nullMap).isEmpty() to fail with a useful failure message instead of throwing NullPointerException (and similarly for other "bogus" values, such as negative sizes). (da5d6e9)
• Made Kotlin's isInstanceOf(Int::class.java) (and Java's isInstanceOf(int.class)) a valid way to check for Int/Integer instances. (974ef19)
• Improved isWithin to pretty-print numbers in its failure messages. (de78553, 07318c2)
• Improved some assertions that print class names to print simpler names (e.g., Integer instead of java.lang.Integer). (0ba72d6)
• Changed ExpectFailure to never generate "value of" lines based on bytecode. This slightly simplifies writing new tests with ExpectFailure and prevents future behavior changes in some ExpectFailure tests that already exist. However, it may also require changes to other existing ExpectFailure tests to remove or change any assertions about the "value of" line. (3caa0e8)
• Our Android minSdkVersion is now 23 (Marshmallow). This follows the minimum of Google's foundational Android libraries, and we expect it to have no practical impact on users. (c85c75c)
• Changed our GWT/J2CL artifact to omit usages of @NullMarked. This was making all our types non-null in those environments, since we don't yet use @Nullable in the GWT/J2CL artifact. (6392d37)
