Find the last non-space character, and the characters of the title after that are the trailing spaces. These are then compared to the lead and trail spaces from the reference control and if they are not exactly the then a bug is reported. > > **When is a bug reported** When either the leading or trailing spaces of the control being tested does not match the equivalent spaces of the reference control exactly. > > **Bug Extra Information** The bug contains the following extra information > > > * **Lead-Trail** Whether this bug report is for the leading or trailing spaces of the control, String > > > > This will be either: > > > > > * “Leading” bug relating to leading spaces > > > * “Trailing” bug relating to trailing spaces > > > > * **Ref** The leading or trailings spaces of the reference string (depending on Lead-Trail value), String > > > > * **Loc** The leading or trailings spaces of the local string (depending on Lead-Trail value), String > > > > **Is Reference dialog needed** This test will not run if the reference controls are not available. > > **False positive bug reports** This is usually not a very important test, so if it generates many false positives then we should consider removing it. > > **Test Identifier** The identifier for this test/bug is “LeadTrailSpaces” > > `pywinauto.tests.leadtrailspaces.``GetLeadSpaces`(*title*)[¶](https://pywinauto.readthedocs.io/en/latest/code/pywinauto.tests.leadtrailspaces.html#pywinauto.tests.leadtrailspaces.GetLeadSpaces "Permalink to this definition") > > Return the leading spaces of the string > > `pywinauto.tests.leadtrailspaces.``GetTrailSpaces`(*title*)[¶](https://pywinauto.readthedocs.io/en/latest/code/pywinauto.tests.leadtrailspaces.html#pywinauto.tests.leadtrailspaces.GetTrailSpaces "Permalink to this definition") > > Return the trailing spaces of the string > > `pywinauto.tests.leadtrailspaces.``LeadTrailSpacesTest`(*windows*)[¶](https://pywinauto.readthedocs.io/en/latest/code/pywinauto.tests.leadtrailspaces.html#pywinauto.tests.leadtrailspaces.LeadTrailSpacesTest "Permalink to this definition") > > Return the leading/trailing space bugs for the windows
