During Erased Data Check the Tool Issues a Failure for "Erased Test Results Data"

[naroner]

In 3.1.23 the tool has started to issue a failure for "Erased Test Results Data" during every check for deleted information.

Based on the DM7 request for SPN 5846 in the proceeding part of the test it appears that the tool is failing to request all the supported SPNs

The report without the CAN log will be fine.

This bug report is for 6.7.15 and 6.7.16. It appears that the logic in

excluding those tests identified in 6.7.15.1.c which did not run before the DM3 was presented to the OBD ECUs. was incorrectly simplified from English to the code (there are a lot of negatives in there and implied in the supporting data).

Incorrectly, instead of verifying the non-initialized tests from 6.1.12, the tool only verified the initialized tests. The implementation of #1039 and #1130 was incorrect.

Because this was confusing, I am restating here for verification:

• initialized means

      boolean initHigh = getTestValue() == 0xFB00 && getTestMinimum() == 0xFFFF && getTestMaximum() == 0xFFFF;
      boolean initLow = getTestValue() == 0x0000 && getTestMinimum() == 0x0000 && getTestMaximum() == 0x0000;
      return initHigh || initLow;

• run, complete, non-initialized, and not initialized all mean the inverse of initialized.
• In 6.7.16.2.a this

  Fail if any OBD ECU erases [test results] excluding those tests identified in 6.7.15.1.c which did not run... meaning

Which I simplified

• Fail if any OBD ECU erases test results excluding those tests identified in 6.7.15.1.c which were initialized...
• Fail if any OBD ECU erases test results including those tests which were not initialized

There are 4 lists maintained to describe different test results for each OBD module:

1. scale test results as found in 6.1.12
2. _initialized_112 as found in 6.1.12. Used in 6.12.10 and 6.9.10.
3. initialized as found in 6.1.12, 6.7.15 and 6.8.11
4. non-initialized as found in 6.4.12, 6.7.15, 6.8.11, 6.12.18, 6.12.10

When testing for erasure (this logic was reversed leading to this bug report):

• if verifying for erasure, only the test results from the initialized list are checked.
• if verifying for no erasure, only the tests results from the non-initialized list are checked.
