Sikuli test-‐suites
• Sikuli is state-‐of-‐the-‐art
• Sikuli does not have support
for test-‐suites! – SO! We
made our own! :P
• Downloadable from the course webpage!
– Includes:
• testSuiteExecutor.sikuli – Main script.
DON’T TOUCH! • outPutWriter.sikuli –
Output. Touch A LOT! • tonA.sikuli
– Helper script (Only works on
Android 1.5 HGVA 320x480) •
tc0001.sikuli – Example test case
that writes Hello World in
browser • tc0002.sikuli – Template
test case

Sikuli test-‐suites
• Use the test-‐executor script •
Import test cases into the
test-‐executor • Test cases must
have the following defini,ons:
– setUp() – tearDown() – runTest()

Wri,ng output
• We have prepared a script-‐file
that you can download from the
course webpage. (outPutWriter.sikuli) – IT
DOES NOT WORK! :P – Edit
defini,ons: • getOutWriter() • getAndroidSim()
• closeAndSaveOutPutFile(group)

outPutWriter.sikuli (Changes)

Issues you WILL encounter!
• TC bug correc,ons are not
recognized by the Test-‐executor
script. – Solu,on: Restart Sikuli
• You cannot copy paste code from
a script to another! Images
must be recaptured. – Solu,on: Import
or recapture
• There is no collec,on of all
standard Sikuli script func,ons.
– Solu,on: Google! “Sikuli +”
-
More issues you WILL encounter!
• Sikuli is extremely resolu,on
sensi,ve! – Solu,on: Make sure you
all have the same screen
resolu,on!
• Timing is oqen a problem –
Solu,on: add wait func,ons when
needed.
• Ex: wait(3) or wait(“img3”,5)
• The image recogni,on is some,mes
too lenient. – Solu,on: set image
recogni,on proper,es to higher than
70%.
