THE TRUE COST OF  OUTSOURCING END-TO-END TESTING

Step 1
Determine how many tests you need
Developers on your team
-
+
Team size is a good indicator of your app’s testing footprint.
Coverage
High
80%
Aiming for 80% E2E test coverage ensures critical paths are well-tested, significantly reducing the risk of undetected bugs.

Step 2
Test creation & management
Time to create each test
2hrs
2 hours per test case on average. This includes outlining, coding, creating test data, and verifying it works.
Time to investigate and fix a failed test
1.5 hrs / test
~1.5 hours on average. This includes re-running the test, reproducing the failure, debugging, PR reviews, and re-deploying the test code.
edit fail rate
Fail rate
7.5%
High velocity teams with daily releases see about 7.5% of tests fail.
Outsource billing rate
$65 / hr
$65/hr is a global average from QA firms in the US, Latin America, Europe, and Asia. Keep in mind that this doesn’t include the “management tax” your team will pay for hands-on management and coaching.
Number of SDETs
By default, we recommend the number of Software Development Engineers in Test (SDETs) based on industry standards.
-
+
SDET Salary
Include at least 1 SDET to set salary.
Step 3
Runs setup
Run Cadence
-
+
You should run the suite at least daily, or more if you deploy continuously.
Run type
Tests run simultaneously across multiple resources. This method can reduce total execution time significantly but might incur higher costs due to the need for more resources.
Cost for parallelization of an individual test
-
$
+
Major vendors charge ~$130/test/mo for up to 25 parallel runs and ~$100/test/mo for 26 or more.
Number of tests ran in parallel per run
-
+
Max:
625
Example: If you have 200 tests, you might run 4 batches of 50.
