Integrate with Mantis

This topic explains how to integrate TestRail with Mantis. There are currently four ways to integrate TestRail with Mantis, namely:

  • Using defect URLs to link test results to Mantis
  • Using the defect plugin for Mantis to push and look up Mantis issues
  • Using reference URLs to link test cases to Mantis
  • Using the reference plugin for Mantis to look up Mantis issues in the References field of TestRail entities such as test cases, test runs, and milestones

You don’t have to use all the listed integration options, and you can mix and match the integration with other tools. Configuring the integration usually only takes a few minutes. This guide explains how to configure the integration and how it works.

You can also find an integration guide on the MantisHub website here.

Defect URLs

The defect URLs are used to let TestRail know how to convert a Defect ID into a URL for your Mantis instance. There are two types of URLs: View URLs and Add URLs.

The Defect View URL is used to build a link to Mantis based on the Defect ID, so you can simply click on an ID to open the issue directly in Mantis.

The Defect Add URL is used to create a link to the issue creation screen inside Mantis. Once the URL is configured, a new Add link appears next to the Defects field in the Add Test Result dialog and the ‘Defects’ menu in TestRail’s Push Defect From Anywhere feature. This link allows you to jump to Mantis’s New Issue form to report a new bug.

If you see the ‘Add’ link, you can copy the ID of your new Mantis issue and enter it into any Defects or References field inside TestRail.

You can configure Mantis’s URLs in TestRail globally under Administration > Integration or on a per-project basis within any project’s settings. 

Use the following example URLs to configure the addresses:

Mantis installation
Defect View Url: http://<your-server>/mantis/view.php?id=%id%
Defect Add Url:  http://<your-server>/mantis/bug_report_page.php

Please make sure to replace <your-server> with the URL of the Mantis server you want to integrate with.

If you have the defect plugin configured, you’ll also be able to hover over the defect ID to view the issue details directly from within TestRail.

Reference URLs

The reference URLs are implemented in a very similar manner to Defect URLs described above. The primary difference is Reference URLs are used for the ‘References’ field on various TestRail entities (instead of the Defects field).

The Reference View URL is configured in the same manner as described above and allows TestRail to create a direct link to a Mantis based on an ID entered into a References field.

The Reference  Add URL is also configured in the same way as the Defect Add URL. Once configured, an ‘Add’ link will appear next to each References field in your instance or project. If you use the ‘Add’ link, you can copy the ID of your new Mantis issue and enter it into any Defects or References field inside TestRail.

If you have the Reference plugin configured, you’ll also be able to hover over a Reference ID to view the issue details directly from within TestRail. Keep reading to learn how to use and configure the Defect and Reference Plugins.

Mantis installation
Reference View Url: http://your-server/mantis/view.php?id=%id%
Reference Add Url:  http://your-server/mantis/bug_report_page.php

Defect Plugin

Defect plugins can be used to implement a deeper bug tracker integration and TestRail comes with a ready-to-use Mantis defect plugin. To configure the defect plugin, select Administration > Integration and select Mantis in the Defect Plugin drop-down list. The next step is to configure all the necessary connection settings in the [connection] category. You can also configure the integration for a specific project by editing a project’s settings.

The Defect Plugin utilizes Mantis’s API, so valid credentials are needed to connect to the API. You can enter a single set of credentials here for all Mantis users. or you can insert User Variables to allow each TestRail user to configure their own credentials. These credentials may be a combination of an email address or username with a password or API key.


We strongly recommend configuring User Variables. You can learn more about configuring these in our User Variables documentation

With the Defect Plugin configured, the option to push a new defect will appear in the Defect from Anywhere menu, as well as in the Add Result dialog within a test run. This dialog allows you to create a new issue in Mantis without leaving TestRail.


Once the test result is added, hovering the mouse cursor over a case ID will open a window with useful information and status details about the case in Mantis.


Plugin customizations require the ‘Mantis_REST’ Defect and Reference plugin, available with TestRail 6.5 and later.


The Mantis defect plugin was built to work with a standard Mantis configuration. TestRail allows you to customize the fields which appear in the Push dialog as well as when hovering over Defect IDs. Preconfigured push fields and hover fields can be set to ‘on’ or ‘off’ in their respective [push.fields] and [hover.fields] sections, or change the order in which they appear by the fields in each section.

Please keep in mind some fields (such as the title field) are always enabled and may not appear in these sections due to always beings required by either TestRail or Mantis.

The Mantis Defect Plugin also supports modifying field properties as well as custom fields.

In addition to enabling, disabling, or re-organizing fields as described above, it’s also possible to change additional options per field. To do this, you would define a section for the field, such as [push.field.description], and specify additional options within this section.

label=Detailed Description

Please see below for a full list and explanation of the available field options:

Option Description
label Specifies the display name of the field in the Push Defect dialogue (Required for custom fields)
size Specifies whether the field is displayed as a compact field (compact) or uses the full width of the dialogue (full)
remember Specifies if previously selected values for this field should be remembered and restored the next time the Push Defect dialogue is opened
required Specifies if this field is mandatory or optional and whether users are required to enter a value for this field in the Push Defect dialogue
type Specifies the type of this field, please see section Custom fields below for a list of supported field types (Required for custom fields)

Custom fields

You can also use the above-mentioned approach to add custom fields to TestRail’s Push Defect dialogue. To do this, simply add a line with your custom field to the [push.fields] section to add a field. Custom fields are designated by customfield_<id>.

# ...

Then, add a [field.settings.customfield_<id>] section. This section is required so the plugin can push and/or retrieve data from your tool.

Custom field information can be obtained through a GET Projects request, as described in the MantisHub API documentation here. The following is an example of custom field configuration:


The following field types are supported:

Field Type Description
date A string field that accepts a YYYY-MM-DD or similarly structured date value. Formatting may depend on the integrated tool’s requirements
datetime A string field that accepts a YYYY-MM-DD HH:MM or similarly structured date and time value. Formatting may depend on the integrated tool’s requirements
dropdown A dropdown list that allows users to select one of the multiple options
string A small free-text field for up to 250 characters
text A large free-text field without practical size limitations


The Mantis Defect Plugin supports submitting attachments to Mantis as well. This field can be turned on and off, but cannot be customized. To submit one or more attachments to Mantis, simply drag the attachment to the attachments or description areas of the push dialog or click on the area to choose an attachment from your file system.

Reference Plugin

Reference plugins can be used to retrieve additional information from IDs entered into the References field of TestRail entities, such as test cases, test runs, and milestones. The Reference Plugin is configured on the References tab of the integration settings, in the same manner, the Defect Plugin is configured.

The plugin supports hovering over Reference IDs but does not support a Push dialog for the References field. It is also possible to customize the fields which appear via link hovering and add custom fields, as described above.

If you have the Defect Plugin already configured for Mantis, you can simply copy your [connection] and [hover.fields] sections from the Defect Plugin into the Reference plugin configuration. Alternatively, you can choose different fields to be displayed for References and Defects.

Additional Customizations

TestRail also supports custom defect plugins. If your team uses TestRail Server, it is possible to further customize the defect plugin (or build your own) to support additional field types or other data. Please see our Defect plugins documentation for additional information.
