xbot.framework 0.5.2

Introduction

xbot is a lightweight, easy-to-use, and extensible test automation framework.

Installation

Install xbot via pip:

pip install xbot.framework

Type xbot --help to check:

$ xbot --help
usage: xbot [-h] [-d DIRECTORY] [-b TESTBED] [-s TESTSET] [-f {verbose,brief}] [-v] {init,run}

positional arguments:
{init,run}

optional arguments:
-h, --help            show this help message and exit
-d DIRECTORY, --directory DIRECTORY
                        directory to init (required by `init` command)
-b TESTBED, --testbed TESTBED
                        testbed filepath (required by `run` command)
-s TESTSET, --testset TESTSET
                        testset filepath (required by `run` command)
-f {verbose,brief}, --outfmt {verbose,brief}
                        output format (option for `run` command, options: verbose/brief, default: brief)
-v, --version         show program's version number and exit

Getting Started

Initialize a test project:

$ xbot init -d ./testproj
Initialized ./testproj

The test project directory structure:

Testbed example(testbeds/testbed_example.yml):

# Testbed is used to store the information about the test environment.
# The information can be accessed by self.testbed.get() in the testcases.
example:
  key1: value1
  key2: 
    key2-1: value2-1
    key2-2: value2-2
  key3:
    - value3-1
    - value3-2
    - value3-3
  key4:
    - name: jack
      age: 20
    - name: tom
      age: 30

Testset example(testsets/testset_example.yml):

# Testset is used to organize testcases to be executed.
tags:  # `exclude` has higher priority than `include`.
  include:  # Include testcases with these tags.
    - tag1
  exclude:  # Exclude testcases with these tags.
    - tag2
paths:
  - testcases/examples/pass/tc_eg_pass_get_values_from_testbed.py
  - testcases/examples/pass/tc_eg_pass_create_dirs_and_files.py
  # Recursively include all testcases in the directory, 
  # only match files with the prefix 'tc_' and suffix '.py'.
  - testcases/examples/nonpass/

Run the testcases(must execute under the test project directory):

$ xbot run -b testbeds/testbed_example.yml -s testsets/testset_example.yml 
(1/11)   PASS     0:00:01  tc_eg_pass_get_values_from_testbed

Testcase Development

Testcases are stored in the testcases subdirectory, below is a example(testcases/examples/pass/tc_eg_pass_create_dirs_and_files.py):

import os
import tempfile
import shutil

from xbot.framework.utils import assertx
from lib.testcase import TestCase


class tc_eg_pass_create_dirs_and_files(TestCase):
    """
    Test creating directories and files.
    """
    TIMEOUT = 60
    FAILFAST = True
    TAGS = ['tag1']

    def setup(self):
        """
        Prepare test environment.
        """
        self.workdir = tempfile.mkdtemp()
        self.info('Created workdir: %s', self.workdir)

    def step1(self):
        """
        Create a subdirectory 'dir' under the temporary working directory and check if it is created successfully.
        """
        self.dir1 = os.path.join(self.workdir, 'dir1')
        os.mkdir(self.dir1)
        assertx(os.path.exists(self.dir1), '==', True)

    def step2(self):
        """
        Create an empty file 'file1' under 'dir1' and check if it is created successfully.
        """
        self.file1 = os.path.join(self.dir1, 'file1')
        open(self.file1, 'w').close()
        assertx(os.path.exists(self.file1), '==', True)

    def step3(self):
        """
        Write 'hello world' to 'file1' and check if it is written successfully.
        """
        with open(self.file1, 'w') as f:
            f.write('hello world')
        with open(self.file1, 'r') as f:
            assertx(f.read(), '==', 'hello world')

    def teardown(self):
        """
        Clean up test environment.
        """
        shutil.rmtree(self.workdir)
        self.info('Removed workdir: %s', self.workdir)
        self.sleep(1)

• Testcase MUST inherit from the TestCase base class;
• Testcase MUST implement the preset steps in the setup method, write pass if there are no specific steps;
• Testcase MUST implement the cleanup steps in the teardown method, write pass if there are no specific steps;
• Test steps are named in the form of step1, step2, ..., the number at the end is the execution order;
• The TIMEOUT attribute defines the maximum execution time of the testcase(unit: seconds), the testcase will be forced to end and the result will be set to TIMEOUT if it exceeds the time limit;
• When FAILFAST attribute is True, the subsequent test steps will be skipped and the teardown will be executed immediately if a test step fails;
• The TAGS attribute defines the testcase tags, which can be used to filter testcases to be executed in the testset;

Test libraries development

Test libraries are stored in the lib subdirectory, write the test libraries according to the business requirements, import and use them in the testcases.

用例开发

测试用例存放在工程目录的 testcases 子目录下，以下为 testcases/examples/pass/tc_eg_pass_create_dirs_and_files.py 用例内容:

import os
import tempfile
import shutil

from xbot.framework.utils import assertx
from lib.testcase import TestCase


class tc_eg_pass_create_dirs_and_files(TestCase):
    """
    Test creating directories and files.
    """
    TIMEOUT = 60
    FAILFAST = True
    TAGS = ['tag1']

    def setup(self):
        """
        Prepare test environment.
        """
        self.workdir = tempfile.mkdtemp()
        self.info('Created workdir: %s', self.workdir)

    def step1(self):
        """
        Create a subdirectory 'dir' under the temporary working directory and check if it is created successfully.
        """
        self.dir1 = os.path.join(self.workdir, 'dir1')
        os.mkdir(self.dir1)
        assertx(os.path.exists(self.dir1), '==', True)

    def step2(self):
        """
        Create an empty file 'file1' under 'dir1' and check if it is created successfully.
        """
        self.file1 = os.path.join(self.dir1, 'file1')
        open(self.file1, 'w').close()
        assertx(os.path.exists(self.file1), '==', True)

    def step3(self):
        """
        Write 'hello world' to 'file1' and check if it is written successfully.
        """
        with open(self.file1, 'w') as f:
            f.write('hello world')
        with open(self.file1, 'r') as f:
            assertx(f.read(), '==', 'hello world')

    def teardown(self):
        """
        Clean up test environment.
        """
        shutil.rmtree(self.workdir)
        self.info('Removed workdir: %s', self.workdir)
        self.sleep(1)

• 用例 必须 继承自 TestCase 基类；
• 用例 必须 在 setup 方法内实现预置步骤，如无具体步骤则写 pass；
• 用例 必须 在 teardown 方法内实现清理步骤，如无具体步骤则写 pass；
• 测试步骤以 step1, step2, ... 这样的方式命名，末尾数字为执行顺序；
• TIMEOUT 属性定义测试用例最大执行时长(单位：秒)，超过该时长将被强制结束且置结果为 TIMEOUT；
• FAILFAST 属性为 True 时，当某个测试步骤失败时，则会跳过后续测试步骤立即执行清理步骤；
• TAGS 属性定义用例 标签，可用于测试套中对待执行测试用例列表进行筛选；

测试库开发

测试库存放在工程目录的 lib 子目录下，根据业务开发所需测试库放入该目录下，然后在测试用例中导入使用即可。
