Generally, regression testing is performed in
order to assure that current functionality
operates appropriately, and all code
modifications did not break the work of other
systems.

Executing software product testing, the
specialists also execute retesting to ensure that
the certain defect was fixed and all
functionality works correctly.

What Are the Differences Between Regression
Checking and Retesting?

• Error verification is not included into
  regression testing, comparing to retesting.
• Regression testing cannot be conducted
  simultaneously with rechecking which has higher
  priority and is performed before regression
  testing.

What Are the Differences Between Regression
Checking and Retesting?

• Automation is applied only to regression tests,
  retests are not automated.
• Absolutely all tests are rechecked under
  regression testing, while under retesting - only
  the failed ones.
• Checking the unforeseen indirect factors is the
  goal of regression testing. Retesting is
  fulfilled to confirm that original features
  operate as it was expected.

What Are the Differences Between Regression
Checking and Retesting?

• Regression checking is executed in the case when
  new system features were added or the
  modifications or improvements of the code itself
  were performed. Retesting is conducted, using the
  same data and in the same environment as before
  but on the new build already.

What Are the Differences Between Regression
Checking and Retesting?

• The test cases for regression testing may be
  created on the basis of project specification or
  other documentation and also on the basis of the
  ready bug reports. Retesting test cases may be
  available only after completing the test process
  itself.
