218-218: Improve the verbose flag description for test commandThe description could be more specific about what additional information is shown in verbose mode, particularly regarding the pocket-ic replica logs mentioned in the changelog.
Consider updating the description:
- .option('--verbose', 'Verbose output') + .option('--verbose', 'Show detailed output including replica logs')cli/commands/replica.ts (1)
18-18: Adjust spacing around optional property operator for consistencyIn TypeScript, the optional property operator
?is typically placed immediately after the property name without a space. Adjusting this improves code consistency and readability.Apply this diff to correct the spacing:
-type ?: 'dfx' | 'pocket-ic' | 'dfx-pocket-ic'; +type?: 'dfx' | 'pocket-ic' | 'dfx-pocket-ic';

Simplify DFX process arguments construction for better readability
The current construction of the DFX arguments array involves including empty strings and filtering them out, which can reduce readability. Consider constructing the array more explicitly to enhance clarity.
Apply this diff to simplify the code:
-this.dfxProcess = spawn('dfx', ['start', this.type === 'dfx-pocket-ic' ? '--pocketic' : '', '--clean', (this.verbose ? '' : '-qqqq'), '--artificial-delay', '0'].filter(x => x).flat(), {cwd: this.dir});
+const dfxArgs = ['start', '--clean', '--artificial-delay', '0'];
+if (this.type === 'dfx-pocket-ic') {
+ dfxArgs.push('--pocketic');
+}
+if (!this.verbose) {
+ dfxArgs.push('-qqqq');
+}
+this.dfxProcess = spawn('dfx', dfxArgs, {cwd: this.dir});This approach enhances readability by explicitly constructing the arguments array.

🛠️ Refactor suggestion
Ensure critical errors are always logged regardless of verbose setting
Currently, critical errors such as socket binding failures may not be logged if verbose is false, which could hinder debugging. Consider adjusting the error handling to always log critical errors.
Apply this diff to log critical errors irrespective of the verbose flag:
this.dfxProcess.stderr.on('data', (data) => {
- if (this.verbose) {
- console.error('DFX:', data.toString());
- }
+ console.error('DFX:', data.toString());
if (data.toString().includes('Failed to bind socket to')) {
console.error(chalk.red(data.toString()));
console.log('Please try again after some time');
process.exit(11);
}
});This ensures that error messages are always output to the console, aiding in troubleshooting.

Handle potential errors when parsing DFX version
The current implementation may throw an error if dfxVersion is not a valid semantic version string, potentially crashing the application. It's important to validate the version string and handle exceptions to ensure robustness.
Apply this diff to handle invalid version strings:
if (replicaType === 'pocket-ic' && !config.toolchain?.['pocket-ic']) {
let dfxVersion = getDfxVersion();
- if (!dfxVersion || new SemVer(dfxVersion).compare('0.24.1') < 0) {
+ if (!dfxVersion) {
+ console.log(chalk.red('Unable to determine dfx version. Please ensure dfx is installed.'));
+ process.exit(1);
+ }
+ let parsedVersion;
+ try {
+ parsedVersion = new SemVer(dfxVersion);
+ } catch (error) {
+ console.log(chalk.red(`Invalid dfx version: ${dfxVersion}. Please update dfx to version >=0.24.1.`));
+ process.exit(1);
+ }
+ if (parsedVersion.compare('0.24.1') < 0) {
console.log(chalk.red('Please update dfx to version >=0.24.1 or specify pocket-ic version in mops.toml'));
process.exit(1);
}
else {
replicaType = 'dfx-pocket-ic';
}
}This modification ensures that invalid or malformed version strings are handled appropriately.
