Following code:
import mimetypes
file_name = 'ipho2001.m4v'
mimetypes.guess_type(file_name)
On python 2.7.13 it returns ('video/x-m4v', None)
On python 3.6.2 it returns ('video/x-m4v', None)
On python 3.7.3 it returns (None, None)
On python 3.8.2 it returns (None, None)
Why? and how to recognise mimetype in python3.7.3?
Not sure why (I will accept a detailed answer if someone will post it). But this is how I have solved it:
mimetypes.add_type('video/x-m4v', '.m4v')

I have a python application that has an option "-y" to end its procedure in a ipython terminal with all objects created ready for an interactive manipulation.
I'm trying to think in how can I design a pytest that could allow me, somehow, to interact with this terminal, to check if objects are there in a python session, exit, and then capture the results for assert (I know how to use capsys for example).
During my attempts (all failed so far) I got a suggestion to use pytest -s option which, obviously, is not my case.
So I have this example:
go_to_python.py
import argparse
import random
parser = argparse.ArgumentParser()
parser.add_argument(
"-y",
"--ipython",
action="store_true",
dest="ipython",
help="start iPython interpreter")
args = parser.parse_args()
if __name__ == "__main__":
randomlist = []
for i in range(0, 5):
n = random.randint(1, 30)
randomlist.append(n)
if args.ipython:
import IPython
IPython.embed(colors="neutral")
How could I create a test that could assert that randomlist is inside the ipython session?
I am trying to run gsutil in Scala, but it doesn't work unless I explicitly put .cmd in the code. I don't like this approach, since others I work with use Unix systems. How do I let Scala understand that gsutil == gsutil.cmd? I could just write a custom shell script and add that to path, but I'd like a solution that doesn't include scripting.
I have already tried with various environment variables (using IntelliJ, don't know if it's relevant). I have tried adding both /bin and /platform/gsutil to path, neither works (without .cmd at least). I have also tried giving full path to see if it made a difference, it didn't.
Here is the method that uses gsutil:
def readFilesInBucket(ss: SparkSession, bucket: String): DataFrame = {
import ss.implicits._
ss.sparkContext.parallelize((s"gsutil ls -l $bucket" !!).split("\n")
.map(r => r.trim.split(" ")).filter(r => r.length == 3)
.map(r => (r(0), r(1), r(2)))).toDF(Array("Size", "Date", "File"): _*)
}
This is my first ever question on SO, I apologize for any formattic errors there may be.
EDIT:
Found out, that even when I write a script like this:
exec gsutil.cmd "$#"
called just gsutil in the same folder, it spits out the same error message as before: java.io.IOException: Cannot run program "gsutil": CreateProcess error=2, The system cannot find the file specified.
It works if I write gsutil in git bash, which otherwise didn't work without the script.
Maybe just use a different version whether you're on Windows or *nix system?
Create some helper:
object SystemDetector {
lazy val isWindows = System.getProperty("os.name").startsWith("Windows")
}
And then just use it like:
def readFilesInBucket(ss: SparkSession, bucket: String): DataFrame = {
import ss.implicits._
val gsutil = if(SystemDetector.isWindows) "gsutil.cmd" else "gsutil"
ss.sparkContext.parallelize((s"$gsutil ls -l $bucket" !!).split("\n")
.map(r => r.trim.split(" ")).filter(r => r.length == 3)
.map(r => (r(0), r(1), r(2)))).toDF(Array("Size", "Date", "File"): _*)
}
Even after a successful execution of my tests in DeviceFarm, I get an empty screenshots report. I have kept my code as simple as below -
from appium import webdriver
import time
import unittest
import os
class MyAndroidTest(unittest.TestCase):
def setUp(self):
caps = {}
self.driver = webdriver.Remote("http://127.0.0.1:4723/wd/hub", caps)
def test1(self):
self.driver.get('http://docs.aws.amazon.com/devicefarm/latest/developerguide/welcome.html')
time.sleep(5)
screenshot_folder = os.getenv('SCREENSHOT_PATH', '/tmp')
self.driver.save_screenshot(screenshot_folder + 'screen1.png')
time.sleep(5)
def tearDown(self):
self.driver.quit()
if __name__ == '__main__':
suite = unittest.TestLoader().loadTestsFromTestCase(MyAndroidTest)
unittest.TextTestRunner(verbosity=2).run(suite)
I tested on a single device pool -
How can I make this work ?
TIA.
Missing a slash (/) before the filename (i.e., screen1.png). Line 15 should be as below -
self.driver.save_screenshot(screenshot_folder + '/screen1.png')
Though I'm not sure exactly how to write this to a file in Device Farm here are the appium docs for the screenshot endpoint and a python example.
https://github.com/appium/appium/blob/master/docs/en/commands/session/screenshot.md
It gets a base 64 encoded string which then we would just need to save it somewhere like the appium screenshot dir the other answers mentioned. Otherwise we could also save it in the /tmp dir and then export it using the custom artifacts feature.
Let me know if that link helps.

I'm trying to do sbt flywayMigrate -Denvi=foo but the system property envi is not being set. Pointers for debugging is greatly appreciated as I haven't been successful in identifying the cause of this issue for hours now. No question in SO or anywhere else have had this issue so far.
In build.sbt, this will be used as a variable.
lazy val envi = sys.props.getOrElse("envi", "default")
Using sys.env.get("ENVI") instead is currently not an option due to shared/team repo considerations.
sbt console -Denvi=foo
scala> sys.props.get("envi")
res0: Option[String] = None
scala> sys.props.getOrElse("envi", "default")
res1: Option[String] = default
scala, sbt installed using brew
You have to put the environment variable before the command:
sbt -Denvi=foo console
otherwise it will be passed as an argument to the main class instead of to the JVM.
Alternatively you can set the environment in the JAVA_OPTS variable before starting sbt:
export JAVA_OPTS="-Denvi=foo"
sbt console
scala> sys.props.getOrElse("envi", "default")
res0: String = foo
I have to go to the path of an application to deploy it, I tried using scala.sys.process and did "cd /home/path/somepath" !
It is throwing an exception, Can anyone guide me how I can go to the directory, I cannot deploy it using absolute path because of the dependency the run file has.
Thanks in advance
Although this question is a couple of years old, it's a good question.
To use scala.sys.process to execute something from a specific working directory, pass the required directory as a parameter to ProcessBuilder, as in this working example:
import scala.sys.process._
val scriptPath = "/home/path/myShellScript.sh"
val command = Seq("/bin/bash","-c",scriptPath)
val proc = Process(command,new java.io.File("."))
var output = Vector.empty[String]
val exitValue = proc ! ProcessLogger (
(out) => if( out.trim.length > 0 )
output +:= out.trim,
(err) =>
System.err.printf("e:%s\n",err) // can be quite noisy!
)
printf("exit value: %d\n",exitValue)
printf("output[%s]\n",output.mkString("\n"))
If the goal instead is to insure that the environment of the caller defaults to a specific working directory, that can be accomplished by setting the required working directory before launching the jvm.
