How to rewrite data-driven test suites of JUnit 3 in Junit 4?
- by rics
I am using data-driven test suites running JUnit 3 based on Rainsberger's JUnit Recipes.
The purpose of these tests is to check whether a certain function is properly implemented related to a set of input-output pairs.
Here is the definition of the test suite:
public static Test suite() throws Exception {
TestSuite suite = new TestSuite();
Calendar calendar = GregorianCalendar.getInstance();
calendar.set(2009, 8, 05, 13, 23); // 2009. 09. 05. 13:23
java.sql.Date date = new java.sql.Date(calendar.getTime().getTime());
suite.addTest(new DateFormatTestToString(date, JtDateFormat.FormatType.YYYY_MON_DD, "2009-SEP-05"));
suite.addTest(new DateFormatTestToString(date, JtDateFormat.FormatType.DD_MON_YYYY, "05/SEP/2009"));
return suite;
}
and the definition of the testing class:
public class DateFormatTestToString extends TestCase {
private java.sql.Date date;
private JtDateFormat.FormatType dateFormat;
private String expectedStringFormat;
public DateFormatTestToString(java.sql.Date date, JtDateFormat.FormatType dateFormat, String expectedStringFormat) {
super("testGetString");
this.date = date;
this.dateFormat = dateFormat;
this.expectedStringFormat = expectedStringFormat;
}
public void testGetString() {
String result = JtDateFormat.getString(date, dateFormat);
assertTrue( expectedStringFormat.equalsIgnoreCase(result));
}
}
How is it possible to test several input-output parameters of a method using JUnit 4?
This question and the answers explained to me the distinction between JUnit 3 and 4 in this regard.
This question and the answers describe the way to create test suite for a set of class but not for a method with a set of different parameters.
