Class IOUtilsTestCase

java.lang.Object
  junit.framework.Assert
      junit.framework.TestCase
          org.apache.commons.io.testtools.FileBasedTestCase
              org.apache.commons.io.IOUtilsTestCase

All Implemented Interfaces:

junit.framework.Test

public class IOUtilsTestCase
extends FileBasedTestCase

This is used to test IOUtils for correctness. The following checks are performed:

• The return must not be null, must be the same type and equals() to the method's second arg
• All bytes must have been read from the source (available() == 0)
• The source and destination content must be identical (byte-wise comparison check)
• The output stream must not have been closed (a byte/char is written to test this, and subsequent size checked)

Due to interdependencies in IOUtils and IOUtilsTestlet, one bug may cause multiple tests to fail.

testCharSequenceToInputStream

public void testCharSequenceToInputStream()
                                   throws java.lang.Exception

Test for IOUtils#toInputStream(CharSequence) and IOUtils#toInputStream(CharSequence, String). Note, this test utilizes on IOUtils#toByteArray(java.io.InputStream) and so relies on testInputStreamToByteArray() to ensure this method functions correctly.

Throws:

java.lang.Exception - on error

testStringToInputStream

                             throws java.lang.Exception

Test for IOUtils#toInputStream(String) and IOUtils#toInputStream(String, String). Note, this test utilizes on IOUtils#toByteArray(java.io.InputStream) and so relies on testInputStreamToByteArray() to ensure this method functions correctly.

Throws:

java.lang.Exception - on error

testByteArrayToOutputStream

public void testByteArrayToOutputStream()
