How To Rape Ur Job

import unittest import pytest class MyTestCase(unittest.TestCase):    @pytest.fixture(autouse=True)    def capfd(self, capfd):        self.capfd = capfd    def test_list_not_well_format(self):        print("Hello World")        out, err = self.capfd.readouterr()        print(f"out: {out}\nerr: {err}")        self.assertTrue("Hello World" in out)

PYTEST COMMAND:

pytest test.py -o junit_family=xunit2 - junitxml=test-reports/junit.xml

We will run a UI test case in a container, so we need to run Selenium in another container. But how can I access selenium server from test container?

Run selenium

docker pull selenium/standalone-chrome-debug:latest docker run --rm -d -p 4444:4444 --name selenium -v /dev/shm:/dev/shm selenium/standalone-chrome-debug:latest

add link for test container

docker build -t testContainer . docker run --name testContainer --link selenium -d testContainer

https://hub.docker.com/_/microsoft-mssql-server

docker pull mcr.microsoft.com/mssql/server:2017-latest

If we try to monitor the system performance, e.g CPU, memory ...., we can use top or other command tools.

But there is another good choice, dstat.

Official web site: http://dag.wiee.rs/home-made/dstat/

If you try to download the dstat, you can find the rpm / deb binary from https://pkgs.org/download/dstat

you also can find the commnads from the web site:

If you need to use the csv to show the chart, you can use the web to generate the graph.

Here is a link to the official Docker documentation for proxy HTTP:https://docs.docker.com/config/daemon/systemd/#httphttps-proxy

A quick outline:

First, create a systemd drop-in directory for the Docker service:

mkdir /etc/systemd/system/docker.service.d

Now create a file called /etc/systemd/system/docker.service.d/http-proxy.conf that adds the HTTP_PROXY environment variable:

[Service] Environment="HTTP_PROXY=http://proxy.example.com:80/"

If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment variable:

Environment="HTTP_PROXY=http://proxy.example.com:80/" Environment="NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com"

Flush changes:

$ sudo systemctl daemon-reload

Verify that the configuration has been loaded:

$ sudo systemctl show --property Environment docker Environment=HTTP_PROXY=http://proxy.example.com:80/

Restart Docker:

sudo docker pull postgres:9.6

docker run --name postgres -p 5432:5432 -e POSTGRES_USER=admin -e POSTGRES_PASSWORD=p@ssw0rd -e -d postgres:9.6

If you need to use session in Flask, you need to set up the security key. You can use SHA512 to make your security key.  

If we want to find some keyword in a string, we will use “break” to stop the loop when we find any keyword we want.

for word in ['one','two']: if word in 'some one long two phrase three': print('find') break

As a DevOps, you must learn how to set up your environment, such as Chef, Ansible.

For me, I think fabric, python SSH2 library, is faster and more flexible.

If we want to do any HTTP/HTTPS requests with Python, Requests is the most easy-used library for HTTP/HTTPS requests.

But if we want to get data from the HTTPS site without certifications, we will get the warning message as below.

/venv/lib/python3.6/site-packages/urllib3/connectionpool.py:857: InsecureRequestWarning: Unverified HTTPS request is being made. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings  InsecureRequestWarning)

So, how to hide the warning message?

Download and install Chrome sudo apt-get install libxss1 libappindicator1 libindicator7 wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb sudo dpkg -i google-chrome*.deb sudo apt-get install -f

Download and unzip chromedriver wget https://chromedriver.storage.googleapis.com/2.40/chromedriver_linux64.zipunzip chromedriver_linux64.zip

Download JAVA sudo add-apt-repository ppa:webupd8team/java sudo apt-get update

Download Selenium

Wget https://selenium-release.storage.googleapis.com/3.10/selenium-server-standalone-3.10.0.jar

Install xvfb

sudo apt-get update && sudo apt-get install -y xfonts-100dpi xfonts-75dpi xfonts-scalable xfonts-cyrillic xvfb x11-apps  imagemagick firefox google-chrome-stable

Run Selenium with xvfb

we can use ssh to connect to AWS server, so we also can use scp to connect to AWS server and transfer file to local.

File path on AWS: /home/user/ubuntu/file.txt You can use the command to download

Steps

Windows not support makecert now, so you can use “New-SelfSignedCertificate”
