Advanced Search capabilities

  • Bugzilla has two kinds of search:
    • It has Google-like bug search which is easy to use, and it also searches the complete text of a bug.
    • It provides you a really advanced search system where you'll create any kind of search that you simply want like time-based searches (For example, you would like to see the list of bugs whose priority has been changed since last two days).

Email Notifications controlled by user preferences

  • You will get an email if any changes are made within the Bugzilla, and therefore the notifications that you simply get on which bug is completely controlled by the user preferences.

Bug lists in multiple formats

  • Reports and Charts once you search for the bugs, then you'll get the bug lists in multiple formats like Atom, iCalendor format.
  • The iCalendor format is used once you are using the time tracking feature in Bugzilla.
  • There are even more formats available in Bugzilla like printable format that contains the details of all the bugs, CSV format used for importing bug list into spreadsheets.

Scheduled reports by email

  • Bugzilla is a system which will send you, users or a group that you specify the results of a search on a schedule that you have mentioned.

Automatic Duplicate Bug Detection

  • When you are filing a new bug, and once you type the summary for the bug, then the system search for similar bugs.
  • If the system finds the similar bugs, then it allows the user to add themselves within the CC list of 1 of these bugs rather than creating a new one.

Under Component, I select Mobile, and under the Status section, I selected New. I selected Severity as a vertical axis and Assignee as a horizontal axis.

Step 3

Duplicates

  • In Bugzilla, duplicates are the most commonly reported bugs. Duplicates contain the field, i.e., Dupe Count that counts the amount of direct and indirect of bugs. This helps in minimizing the amount of duplicate bugs that are entered into Bugzilla. It also helps the QA tester to log a new defect instead of a defect that exist already. It also helps the stakeholders to find the bug that are reopened.

How to use a duplicate list

  • Review the frequently reported bugs.
  • If your bug is listed in reported bug list then click on the bug number to verify that you simply have found the bug, and you'll also add the extra information in comments.
  • If your bug isn't listed during a bug list, then you'll perform the following steps:
    • Try to locate the similar bug that has already been filed.
    • If your bug is found then you're free to add the extra information in comments.
    • If your bug isn't listed within the bug list then File a new bug.

The following are the steps required to use a duplicate list:

Step 1

  • Click on the Reports.

Step 2

  • Click on the Duplicates as shown below:
