Here are some quick (and probably incomplete) notes about setting up
SyncEvolution as HTTP server for client-test runs using just the local
account and machine.

# 1. run client-test like this:
CLIENT_TEST_SERVER=syncevolution --help

# 2. set the URL (using IPv4 here, in case that "localhost" expands to IPv6, which
#    can be problematic):
for i in 1 2; do
   syncevolution --configure --sync-property syncURL=http://127.0.0.1:9000/syncevolution syncevolution_$i
done

# 3. configure the server, using a separate context with the four standard URIs
#    implemented via files in /tmp, no credential checking, maximum message size
#    which forces the clients to split items (makes testInterruptResume*Big more
#    interesting), low timeout to keep tests going quickly, with device IDs as
#    set by client-test-app.cpp in step 1:
for i in 1 2; do
   syncevolution --configure --template SyncEvolutionClient \
                 --sync-property username= \
                 --sync-property password= \
                 --sync-property maxMsgSize=20000 \
                 --sync-property RetryDuration=20 \
                 syncevolution_client_$i@server
done
syncevolution --configure \
              --source-property type=file:text/vcard:3.0 \
              --source-property evolutionsource=file:///tmp/server_addressbook \
              @server addressbook
syncevolution --configure \
              --source-property type=file:text/calendar:2.0 \
              --source-property evolutionsource=file:///tmp/server_calendar \
              @server calendar
syncevolution --configure \
              --source-property type=file:text/plain:1.0 \
              --source-property evolutionsource=file:///tmp/server_memo \
              @server memo
syncevolution --configure \
              --source-property type=file:text/calendar:2.0 \
              --source-property evolutionsource=file:///tmp/server_todo \
              @server todo
syncevolution --configure --sync-property remoteDeviceId=sc-api-nat syncevolution_client_1@server
syncevolution --configure --sync-property remoteDeviceId=sc-pim-ppc syncevolution_client_2@server

# 4. run the syncevo-dbus-server (necessary when not installed):
syncevo-dbus-server -d 1000000 &

# 5. run http server:
syncevo-http-server http://localhost:9000/syncevolution &

# 6. run testing, here using again file backends:
CLIENT_TEST_SERVER=syncevolution \
CLIENT_TEST_RETRY=t CLIENT_TEST_RESEND=t CLIENT_TEST_SUSPEND=t \
CLIENT_TEST_SOURCES=file_vcard30,file_ical20 \
CLIENT_TEST_EVOLUTION_PREFIX=file:///tmp/test_ \
client-test
