Volcano of Tests

The volcano represents the fact that both checking and exploration are part of the activity we call software testing.


  • The shape of the Test Automation Pyramid refers to healthy test ratios and relative importance. The “volcano ash” cloud follows that pattern:
    • It is on the top, as these tests are typically relevant to the end user, can be relatively complex and costly.
    • In my opinion they are key to achieving customer satisfaction, so the cloud is large.
  • Using tools is not limited to automation. Manual testing should be supported by tools when necessary.
  • “Checking” can be both manual and automated.
