Вивчайте Exploring Test Data Trends with Seaborn | Analyzing and Visualizing Test Data

Seaborn is a powerful Python library built on top of matplotlib, designed to make it easier to create visually appealing and informative statistical graphics. For QA engineers, seaborn offers a range of tools that simplify the process of exploring test data trends, such as execution times, pass/fail rates, and performance variability. Its high-level interface allows you to quickly generate complex plots with minimal code, making it especially useful for identifying patterns, outliers, and relationships within your test datasets. By leveraging seaborn, you can gain deeper insights into your testing process, spot inefficiencies, and communicate results more effectively to your team.

# Sample test execution data
data = {
    "test_name": ["test_login", "test_logout", "test_signup", "test_search", "test_profile", "test_login", "test_signup", "test_search"],
    "status": ["passed", "failed", "passed", "skipped", "passed", "failed", "skipped", "passed"],
    "duration": [1.2, 2.5, 1.0, 0.5, 1.4, 2.7, 0.6, 1.1]
}

df = pd.DataFrame(data)

# Create a boxplot of test execution times grouped by status
sns.boxplot(x="status", y="duration", data=df)
plt.title("Test Execution Times by Status")
plt.ylabel("Duration (seconds)")
plt.xlabel("Test Status")
plt.show()

A boxplot is a valuable visualization for understanding the distribution of test execution times across different statuses, such as passed, failed, or skipped. In a boxplot, the central box represents the interquartile range (the middle 50% of your data), the line inside the box shows the median, and the "whiskers" extend to show the range of the data, excluding outliers. Outliers are displayed as individual points. By examining a boxplot, you can quickly spot which test statuses tend to have longer or more variable execution times, identify potential performance issues, and detect unusually slow or fast test runs. This helps you focus your analysis and troubleshooting where it matters most.

import seaborn as sns
import matplotlib.pyplot as plt

# Reuse the previous DataFrame 'df'

# Create a countplot to show the frequency of each test status
sns.countplot(x="status", data=df)
plt.title("Frequency of Test Statuses")
plt.xlabel("Test Status")
plt.ylabel("Count")
plt.show()
