## JUnitParams 1.0.5 release. Release date : ?

### Deprecated $ method
Utility method `$` was deprecated. It was causing too much problems and we decided not to support it any more. If you wish to keep using it, implement it in your own codebase.

### Automatic class name to class object conversion

```java

    @Test
    @Parameters({"java.lang.Object", "java.lang.String"})
    public void passClassAsString(Class<?> clazz) {
        assertThat(clazz).isIn(java.lang.Object.class, java.lang.String.class);
    }
```

### Support custom annotations for parameter conversion
 
You can create your own annotations for parameter conversion. Just annotate it with `@Param` and pass it a reference to `Converter` implementation.

Example:


```java

    @Retention(RetentionPolicy.RUNTIME)
    @Target(ElementType.PARAMETER)
    @Param(converter = FormattedDateConverter.class)
    public @interface DateParam {

        String format() default "dd.MM.yyyy";
    }

    public static class FormattedDateConverter implements Converter<DateParam, Date> {

        private String format;

        @Override
        public void initialize(DateParam annotation) {
            this.format = annotation.format();
        }

        @Override
        public Date convert(Object param) throws ConversionFailedException {
            try {
                return new SimpleDateFormat(format).parse(param.toString());
            } catch (ParseException e) {
                throw new ConversionFailedException("failed");
            }
        }
    }
```

Usage example:

```java

    @Test
    @Parameters({"2012-12-01"})
    public void testWithConvertedDate(@DateParam Date date) {
        assertThat(...);
    }
```

### CustomParameters

You can create custom annotations for parameter providers. `@FileParameters` have been refactored to use this mechanism and should serve as a perfect usage example.

```java

    @Retention(RetentionPolicy.RUNTIME)
    @Target(ElementType.METHOD)
    @CustomParameters(provider = FileParametersProvider.class)
    public @interface FileParameters {

        String fileLocation();
    
    }

    public class FileParametersProvider implements ParametersProvider<FileParameters> {

        private String fileLocation;
    
        @Override
        public void initialize(FileParameters fileParameters) {
            this.fileLocation = fileParameters.fileLocation();
        }
    
        @Override
        public Object[] getParameters() {
            return paramsFromFile(fileLocation);
        }
        
        ...
    }

```

### @CombinedParameters

Thanks to [piekarskim](https://github.com/piekarskim) The issue #1 is fixed. 
Using this annotation will result in creating a n-fold cartesian product of parameter values effectively testing each possible combination.
Since an example is worth a thousand words:

Such annotated test method:

```java

    @Test
    @CombinedParameters({"a,b", "1,2"})
    public void calledWithCartesianProduct(String character, Integer number) {
    ...
    }
```

Will be called 4 times with parameters:

```
 a  1 
 a  2 
 b  1 
 b  2 
```

## JUnitParams 1.0.4 release. Release date : 2015-01-23

### Configurable test case name
New annotation `@TestCaseName` that can be used for test case name configuration:

```java
  @Test
  @Parameters({ "1,1", "2,2" })
  @TestCaseName("factorial({0}) = {1}")
  public void custom_names_for_test_case(int argument, int result) { }
```

will produce tests with names:

```
factorial(1) = 1
factorial(2) = 2
```

### Allow usage of enums as a data source

Parameters annotation now allows passing Enum values as parameters

```
@Parameters(source = Fruit.class)
```

### Test results filtering fixed

When starting a single test method from within an IDE, the tests results were not shown up properly in the results tab.
Its fixed now thanks to [jerzykrlk](https://github.com/jerzykrlk)
