How to manually run swift-lldb tests?

Development LLDB

I wonder how to manually run swift-lldb tests?

After finding this reply, I tried the following (after building swift via update-checkout and build-script) and got an error:

# Invoked within Swift build directory.
$ lldb/test/dotest.py testcases/lang/swift
WARNING:root:No valid FileCheck executable; some tests may fail...
WARNING:root:(Double-check the --filecheck argument to dotest.py)
The 'lldb' executable cannot be located.  Some of the tests may not be run as a result.

./lldb-dotest -p <TESTNAME> should do it.
If this doesn't work, please let me know.

lldb-dotest works!

How can I use it to run specific tests?

I tried the following with no success:

# Example: trying to run lldb/test/testcases/lang/swift/swiftieformatting.

Have you tried to cd into the bin directory and run
./lldb-dotest -p TestSwiftieFormatting ? [also see previous reply for a generalization]/

cd'ing into bin and running ./lldb-dotest -p TestSwiftieFormatting worked, thanks!
