Checks that the value under test is equal to the given object.

(This allows {@code assertThat(someDouble).isEqualTo(0)} to pass.) </ul> <p><b>Note:</b> This method does not test the {@link Object#equals} implementation itself; it <i>assumes</i> that method is functioning correctly according to its contract.

Returns {@link ComparisonResult#equal} if the arrays are equal. If not equal, returns a string comparing the two arrays, displaying them in the style "[1, 2, 3]" to supplement the main failure message, which uses the style "010203."

@Deprecated final StandardSubjectBuilder check() { return new StandardSubjectBuilder(metadata.updateForCheckCall()); }
Returns a builder for creating a derived subject but without providing information about how the derived subject will relate to the current subject. In most cases, you should provide such information by using {@linkplain #check(String, Object...) the other overload}. @deprecated Use {@linkplain #check(String, Object...) the other overload}, which requires you to supply more information to include in any failure messages.

protected final StandardSubjectBuilder check(String format, @Nullable Object... args) { return doCheck(OldAndNewValuesAreSimilar.DIFFERENT, format, args); }
Returns a builder for creating a derived subject. <p>Derived subjects retain the {@link FailureStrategy} and {@linkplain StandardSubjectBuilder#withMessage messages} of the current subject, and in some cases, they automatically supplement their failure message with information about the original subject. <p>For example, {@link ThrowableSubject#hasMessageThat}, which returns a {@link StringSubject}, is implemented with {@code check("getMessage()").that(actual.getMessage())}. <p>The arguments to {@code check} describe how the new subject was derived from the old, formatted like a chained method call. This allows Truth to include that information in its failure messages. For example, {@code assertThat(caught).hasCauseThat().hasMessageThat()} will produce a failure message that includes the string "throwable.getCause().getMessage()," thanks to internal {@code check} calls that supplied "getCause()" and "getMessage()" as arguments. <p>If the method you're delegating to accepts parameters, you can pass {@code check} a format string. For example, {@link MultimapSubject#valuesForKey} calls {@code check("valuesForKey(%s)", key)}. <p>If you aren't really delegating to an instance method on the actual value -- maybe you're calling a static method, or you're calling a chain of several methods -- you can supply whatever string will be most useful to users. For example, if you're delegating to {@code getOnlyElement(actual.colors())}, you might call {@code check("onlyColor()")}. @param format a template with {@code %s} placeholders @param args the arguments to be inserted into those placeholders

final StandardSubjectBuilder substituteCheck() { return new StandardSubjectBuilder(checkNotNull(metadata)); }
Returns a builder for creating a subject for an object that is "close enough" to the original actual value. <p>This is a niche API: When one {@link Subject} wants to delegate to another, it should normally use {@link #check(String, Object...)}, which augments the failure message by: <ul> <li>specifying which <i>part</i> of the actual value we are asserting about (e.g., "value of: foo.size()") <li>including both the original actual value and the relevant part of that value (e.g., both the collection and its size) </ul> Thus, {@code substituteCheck()} is useful only when the new assertion is still (roughly speaking) "about" the entire actual value. For example, {@link StreamSubject} uses this method to create an {@link IterableSubject} for the contents of the stream. <p>The result of {@code substituteCheck()} should be used carefully. For example, it should <b>never</b> be returned to users unless the new subject has the exact full actual value as the original one had. (As of this writing, we never do that, but that may change someday (b/135436697? b/333091510?).) That's because: <ul> <li>If the assertion is about only a <i>part</i> of the actual value (or about some derived value, as in {@link ObjectArraySubject#asList}), then we should use {@link #check(String, Object...)}, as discussed above. (In some cases, we should instead introduce a non-{@link Subject} type, such as {@link StringSubject.CaseInsensitiveStringComparison}.) <li>Otherwise, we don't want to present an assertion as about the original actual value when it's actually about some "stand-in" value. For example (though this isn't a great example), we wouldn't want for {@code assertThat(stream).isEqualTo(expected)} to use {@code substituteCheck().that(stream.toList())} internally: The test would be comparing the <i>list</i> for equality, but the message would suggest that it's comparing the <i>stream</i>. </ul>
