AssertionsForClassTypes (AssertJ fluent assertions 3.12.0 API)

java.lang.Object
- org.assertj.core.api.AssertionsForClassTypes

Direct Known Subclasses:

AssertionsForInterfaceTypes
```
public class AssertionsForClassTypes
extends Object
```
Java 8 is picky when choosing the right assertThat method if the object under test is generic and bounded, for example if foo is instance of T that extends Exception, java 8 will complain that it can't resolve the proper assertThat method (normally assertThat(Throwable) as foo might implement an interface like List, if that occurred assertThat(List) would also be a possible choice - thus confusing java 8.
This why Assertions have been split in AssertionsForClassTypes and AssertionsForInterfaceTypes (see http://stackoverflow.com/questions/29499847/ambiguous-method-in-java-8-why).

  - assertThatThrownBy
```
public static AbstractThrowableAssert<?,? extends Throwable> assertThatThrownBy(ThrowableAssert.ThrowingCallable shouldRaiseThrowable)
```
    Allows to capture and then assert on a Throwable (easier done with lambdas).
    Java 8 example :
```
  @Test
  public void testException() {
    assertThatThrownBy(() -> { throw new Exception("boom!") }).isInstanceOf(Exception.class)
                                                              .hasMessageContaining("boom");
 }
```
    If the provided ThrowableAssert.ThrowingCallable does not raise an exception, an error is immediately thrown, in that case the test description provided with as(String, Object...) is not honored.
    To use a test description, use catchThrowable(ThrowableAssert.ThrowingCallable) as shown below:
```
 // assertion will fail but "display me" won't appear in the error
 assertThatThrownBy(() -> {}).as("display me")
                             .isInstanceOf(Exception.class);

 // assertion will fail AND "display me" will appear in the error
 Throwable thrown = catchThrowable(() -> {});
 assertThat(thrown).as("display me")
                   .isInstanceOf(Exception.class);
```
    Alternatively you can also use assertThatCode(ThrowingCallable) for the test description provided with as(String, Object...) to always be honored.
    Parameters:
    
    shouldRaiseThrowable - The ThrowableAssert.ThrowingCallable or lambda with the code that should raise the throwable.
    
    Returns:
    
    the created ThrowableAssert.
  - assertThatThrownBy
```
public static AbstractThrowableAssert<?,? extends Throwable> assertThatThrownBy(ThrowableAssert.ThrowingCallable shouldRaiseThrowable,
                                                                                String description,
                                                                                Object... args)
```
    Allows to capture and then assert on a Throwable like assertThatThrownBy(ThrowingCallable) but this method let you set the assertion description the same way you do with as(String, Object...).
    Example:
```
  @Test
  public void testException() {
    // if this assertion failed (but it doesn't), the error message would start with [Test explosive code]
    assertThatThrownBy(() -> { throw new IOException("boom!") }, "Test explosive code")
             .isInstanceOf(IOException.class)
             .hasMessageContaining("boom");
 }
```
    If the provided ThrowingCallable does not raise an exception, an error is immediately thrown.
    The test description provided is honored but not the one with as(String, Object...), example:
```
 // assertion will fail but "display me" won't appear in the error message
 assertThatThrownBy(() -> {}).as("display me")
                             .isInstanceOf(Exception.class);

 // assertion will fail AND "display me" will appear in the error message
 assertThatThrownBy(() -> {}, "display me")
                             .isInstanceOf(Exception.class);
```
    Parameters:
    
    shouldRaiseThrowable - The ThrowableAssert.ThrowingCallable or lambda with the code that should raise the throwable.
    
    description - the new description to set.
    
    args - optional parameter if description is a format String.
    
    Returns:
    
    the created ThrowableAssert.
    
    Since:
    
    3.9.0
  - assertThatExceptionOfType
```
public static <T extends Throwable> ThrowableTypeAssert<T> assertThatExceptionOfType(Class<? extends T> exceptionType)
```
    Entry point to check that an exception of type T is thrown by a given throwingCallable which allows to chain assertions on the thrown exception.
    Example:
```
 assertThatExceptionOfType(IOException.class)
              .isThrownBy(() -> { throw new IOException("boom!"); })
              .withMessage("boom!"); 
```
    This method is more or less the same of assertThatThrownBy(ThrowableAssert.ThrowingCallable) but in a more natural way.
    Type Parameters:
    
    T - the exception type.
    
    Parameters:
    
    exceptionType - the class of exception type.
    
    Returns:
    
    the created ThrowableTypeAssert.
  - assertThatCode
```
public static AbstractThrowableAssert<?,? extends Throwable> assertThatCode(ThrowableAssert.ThrowingCallable shouldRaiseOrNotThrowable)
```
    Allows to capture and then assert on a Throwable more easily when used with Java 8 lambdas.
    Example :
```
 ThrowingCallable callable = () -> {
   throw new Exception("boom!");
 };

 // assertion succeeds
 assertThatCode(callable).isInstanceOf(Exception.class)
                         .hasMessageContaining("boom");

 // assertion fails
 assertThatCode(callable).doesNotThrowAnyException();
```
    If the provided ThrowableAssert.ThrowingCallable does not validate against next assertions, an error is immediately raised, in that case the test description provided with as(String, Object...) is not honored.
    To use a test description, use catchThrowable(ThrowableAssert.ThrowingCallable) as shown below.
```
 ThrowingCallable doNothing = () -> {
   // do nothing
 };

 // assertion fails and "display me" appears in the assertion error
 assertThatCode(doNothing).as("display me")
                          .isInstanceOf(Exception.class);

 // assertion will fail AND "display me" will appear in the error
 Throwable thrown = catchThrowable(doNothing);
 assertThatCode(thrown).as("display me")
                       .isInstanceOf(Exception.class); 
```
    This method was not named assertThat because the java compiler reported it ambiguous when used directly with a lambda :(
    Parameters:
    
    shouldRaiseOrNotThrowable - The ThrowableAssert.ThrowingCallable or lambda with the code that should raise the throwable.
    
    Returns:
    
    The captured exception or null if none was raised by the callable.
    
    Since:
    
    3.7.0
  - catchThrowable
```
public static Throwable catchThrowable(ThrowableAssert.ThrowingCallable shouldRaiseThrowable)
```
    Allows catching a Throwable more easily when used with Java 8 lambdas.
    This caught Throwable can then be asserted.
    
    Example:
```
 @Test
 public void testException() {
   // when
   Throwable thrown = catchThrowable(() -> { throw new Exception("boom!"); });

   // then
   assertThat(thrown).isInstanceOf(Exception.class)
                     .hasMessageContaining("boom");
 } 
```
    Parameters:
    
    shouldRaiseThrowable - The lambda with the code that should raise the exception.
    
    Returns:
    
    The captured exception or null if none was raised by the callable.
    
    See Also:
    
    catchThrowableOfType(ThrowableAssert.ThrowingCallable, Class)
  - catchThrowableOfType
```
public static <THROWABLE extends Throwable> THROWABLE catchThrowableOfType(ThrowableAssert.ThrowingCallable shouldRaiseThrowable,
                                                                           Class<THROWABLE> type)
```
    Allows catching a Throwable of a specific type.
    A call is made to catchThrowable(ThrowingCallable), if no exception is thrown catchThrowableOfType returns null, otherwise it checks that the caught Throwable has the specified type then casts it to it before returning it, making it convenient to perform subtype-specific assertions on the result.
    Example:
```
 class CustomParseException extends Exception {
   int line;
   int column;

   public CustomParseException(String msg, int l, int c) {
     super(msg);
     line = l;
     column = c;
   }
 }

 CustomParseException e = catchThrowableOfType(() -> { throw new CustomParseException("boom!", 1, 5); },
                                               CustomParseException.class);
 // assertions pass
 assertThat(e).hasMessageContaining("boom");
 assertThat(e.line).isEqualTo(1);
 assertThat(e.column).isEqualTo(5);

 // fails as CustomParseException is not a RuntimeException
 catchThrowableOfType(() -> { throw new CustomParseException("boom!", 1, 5); },
                      RuntimeException.class);
```
    Type Parameters:
    
    THROWABLE - the Throwable type.
    
    Parameters:
    
    shouldRaiseThrowable - The lambda with the code that should raise the exception.
    
    type - The type of exception that the code is expected to raise.
    
    Returns:
    
    The captured exception or null if none was raised by the callable.

  - setLenientDateParsing
```
public static void setLenientDateParsing(boolean value)
```
    Instead of using default strict date/time parsing, it is possible to use lenient parsing mode for default date formats parser to interpret inputs that do not precisely match supported date formats (lenient parsing).
    With strict parsing, inputs must match exactly date/time format.
    Example:
```
 final Date date = Dates.parse("2001-02-03");
 final Date dateTime = parseDatetime("2001-02-03T04:05:06");
 final Date dateTimeWithMs = parseDatetimeWithMs("2001-02-03T04:05:06.700");

 Assertions.setLenientDateParsing(true);

 // assertions will pass
 assertThat(date).isEqualTo("2001-01-34");
 assertThat(date).isEqualTo("2001-02-02T24:00:00");
 assertThat(date).isEqualTo("2001-02-04T-24:00:00.000");
 assertThat(dateTime).isEqualTo("2001-02-03T04:05:05.1000");
 assertThat(dateTime).isEqualTo("2001-02-03T04:04:66");
 assertThat(dateTimeWithMs).isEqualTo("2001-02-03T04:05:07.-300");

 // assertions will fail
 assertThat(date).hasSameTimeAs("2001-02-04"); // different date
 assertThat(dateTime).hasSameTimeAs("2001-02-03 04:05:06"); // leniency does not help here
```
    To revert to default strict date parsing, call setLenientDateParsing(false).
    Parameters:
    
    value - whether lenient parsing mode should be enabled or not
  - registerCustomDateFormat
```
public static void registerCustomDateFormat(DateFormat userCustomDateFormat)
```
    Add the given date format to the ones used to parse date String in String based Date assertions like AbstractDateAssert.isEqualTo(String).
    User date formats are used before default ones in the order they have been registered (first registered, first used).
    AssertJ is gonna use any date formats registered with one of these methods :
    Beware that AssertJ will use the newly registered format for all remaining Date assertions in the test suite
    To revert to default formats only, call useDefaultDateFormatsOnly() or AbstractDateAssert.withDefaultDateFormatsOnly().
    Code examples:
```
 Date date = ... // set to 2003 April the 26th
 assertThat(date).isEqualTo("2003-04-26");

 try {
   // date with a custom format : failure since the default formats don't match.
   assertThat(date).isEqualTo("2003/04/26");
 } catch (AssertionError e) {
   assertThat(e).hasMessage("Failed to parse 2003/04/26 with any of these date formats: " +
                            "[yyyy-MM-dd'T'HH:mm:ss.SSS, yyyy-MM-dd'T'HH:mm:ss, yyyy-MM-dd]");
 }

 // registering a custom date format to make the assertion pass
 registerCustomDateFormat(new SimpleDateFormat("yyyy/MM/dd")); // registerCustomDateFormat("yyyy/MM/dd") would work to.
 assertThat(date).isEqualTo("2003/04/26");

 // the default formats are still available and should work
 assertThat(date).isEqualTo("2003-04-26");
```
    Parameters:
    
    userCustomDateFormat - the new Date format used for String based Date assertions.
  - registerCustomDateFormat
```
public static void registerCustomDateFormat(String userCustomDateFormatPattern)
```
    Add the given date format to the ones used to parse date String in String based Date assertions like AbstractDateAssert.isEqualTo(String).
    User date formats are used before default ones in the order they have been registered (first registered, first used).
    AssertJ is gonna use any date formats registered with one of these methods :
    Beware that AssertJ will use the newly registered format for all remaining Date assertions in the test suite
    To revert to default formats only, call useDefaultDateFormatsOnly() or AbstractDateAssert.withDefaultDateFormatsOnly().
    Code examples:
```
 Date date = ... // set to 2003 April the 26th
 assertThat(date).isEqualTo("2003-04-26");

 try {
   // date with a custom format : failure since the default formats don't match.
   assertThat(date).isEqualTo("2003/04/26");
 } catch (AssertionError e) {
   assertThat(e).hasMessage("Failed to parse 2003/04/26 with any of these date formats: " +
                            "[yyyy-MM-dd'T'HH:mm:ss.SSS, yyyy-MM-dd'T'HH:mm:ss, yyyy-MM-dd]");
 }

 // registering a custom date format to make the assertion pass
 registerCustomDateFormat("yyyy/MM/dd");
 assertThat(date).isEqualTo("2003/04/26");

 // the default formats are still available and should work
 assertThat(date).isEqualTo("2003-04-26");
```
    Parameters:
    
    userCustomDateFormatPattern - the new Date format pattern used for String based Date assertions.
  - useDefaultDateFormatsOnly
```
public static void useDefaultDateFormatsOnly()
```
    Remove all registered custom date formats => use only the defaults date formats to parse string as date.
    Beware that the default formats are expressed in the current local timezone.
    Defaults date format are:
    - yyyy-MM-dd'T'HH:mm:ss.SSS
    - yyyy-MM-dd HH:mm:ss.SSS (for Timestamp String representation support)
    - yyyy-MM-dd'T'HH:mm:ss
    - yyyy-MM-dd
    Example of valid string date representations:
    - 2003-04-26T03:01:02.999
    - 2003-04-26 03:01:02.999
    - 2003-04-26T13:01:02
    - 2003-04-26
