Method Details

beforeAll

public void beforeAll(org.junit.jupiter.api.extension.ExtensionContext context)

Handles the beforeAll case. Setting up the context.

Specified by:

beforeAll in interface org.junit.jupiter.api.extension.BeforeAllCallback

Parameters:

context - the current extension context; never null

Throws:

Exception - if anything goes wrong.

beforeEach

public void beforeEach(org.junit.jupiter.api.extension.ExtensionContext context)
                throws Exception

Handles the before each case. Setting the vars in the object.

beforeEach in interface org.junit.jupiter.api.extension.BeforeEachCallback

Parameters:

context - the current extension context; never null

Exception - if anything goes wrong.

uniqueFields

public Set<Field> uniqueFields(Class<?> clazz)

Gets all unique annotation fields for this class and its super class.

Parameters:

clazz - to check.

Returns:

set of fields.

setValueForField

protected void setValueForField(String value,
 Object object,
 Field field)

Sets the value for the field. Really this just ignores the exception.

Parameters:

value - to set.

object - on this object.

field - in this field.

enableSettingTheField

protected void enableSettingTheField(Field field)

This allows us to set the field directly. It will fail if the security manager in play disallows it. We can talk about justifications all we want, but really we know Java is not Smalltalk. Meta programming is limited here. So... we try to do the right thing.

Parameters:

field - to change accessibility for.
